Understanding these factors can provide valuable insights for the development of improved controlled release systems, offering enhanced precision and efficiency in herbicide delivery. Polymer-montmorillonite clay composites carrying 2,4-dichlorophenoxy acetic acid as controlled release systems were prepared by in-situ polycondensation. The intercalated polymeric 2,4-dichlorophenoxy acetic acid composites were characterized using various analytical techniques. Release studies were conducted in aqueous media at different pH levels over an extended period of approximately 80 days. The results revealed the significant influence of various factors on the release rate of the herbicide, including polymer structure, medium composition, percentage of polymer grafting onto clay, clay-to-polymer ratio, and swelling behavior. These findings have important implications for the development of controlled release systems for herbicides. Understanding the factors influencing release rates enables the optimization of composite design and formulation for efficient herbicide delivery. Moreover, this research provides a foundation for future investigations aimed at enhancing the release performance and overall effectiveness of polymer-montmorillonite clay composites. Potential avenues for further research include exploring tailored polymer structures, modifying the clay matrix, and optimizing the clay-to-polymer ratio.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 3","pages":"429 - 444"},"PeriodicalIF":1.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142587810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its structural similarity to myrcene (C10H16), this conjugated diene, offers the possibility of undergoing polymerization using the same method employed for myrcene. This involves the utilization of neodymium trisborohydride as a pre-catalyst activated by boron derivatives in the presence of triisobutyl aluminum. This innovative approach has led to the successful production of 1,4-cis polyocimene, a significant achievement in the field of polymer chemistry. Detailed analysis through the application of 13C NMR and DEPT 135 spectroscopy has shed light on the microstructure of the resulting polyocimene. It has been revealed that the polymer exhibits a predominant microstructure of 1,4‑cis (comprising up to 83.38% of the structure) along with the presence of 1,2-trans isomer (constituting 16.62%). The findings also highlight that the molecular weight distributions of the polymer are relatively broader (PDI > 2). This catalytic system enables the production of polymers that can be used as promising starting materials for bio-based thermoplastic elastomers.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 3","pages":"315 - 320"},"PeriodicalIF":1.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142587844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MSNs were used as fillers and carriers to immobilize polymer components and form three-dimensional grids within the material, thus imparting the absorbent resin with the required mechanical strength. Carboxymethyl chitosan (CTS) was used as the substrate for synthesizing composite water absorbent resin. A composite superabsorbent resin was prepared by grafting copolymerization with acrylamide (AM) and acrylic acid (AA) and it was referred to as MSNs@CTS-g-P(AA-co-AM). The liquid absorption and adsorption performances of heavy metal ions were examined in different environments. The results showed that the water absorption rate of MSNs@CTS-g-P(AA-co-AM) reached 740 g/g at water absorption equilibrium. Compared with known organic/inorganic composite water absorbing resins, the composite resin involving MSNs had good water retention performance, which was evident from the water retention rate reaching a maximum of 91.8% when the resin was dried at 80°C for 6 h. This was attributed to the composite resin forming a stable three-dimensional network structure due to the MSNs, strong salt resistance, and better adsorption performance.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 3","pages":"371 - 379"},"PeriodicalIF":1.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142587812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This catalyst was activated with 0.5 M sulfuric acid solution to increase its Brønsted-type acidity. Polymerization of DXL was carried out in bulk under magnetic stirring at low temperature, leading to the formation of polydioxolane. The Halloysite and synthesized polymer were characterized by several techniques including X-ray fluorescence (XRF), X-ray diffraction (XRD), Infrared spectroscopy (FTIR), and nuclear magnetic resonance (NMR). To assess the dispersing power of the synthesized PDXL and its hydration activity, the setting time, consistence and compressive strength of cement paste and mortar containing poly(1,3-dioxolane) was studied, compared to the commercial polyethylene glycol (PEG) used as reference in this study. The results showed the retarding effect of PDXL on the setting times of cement paste, accompanied by a decrease in normal consistency, which allows its use as superplasticizer or dispersant agent. Thus, PDXL improved the compressive strength of cement mortar compared to PEG polymer effect.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"66 3","pages":"305 - 314"},"PeriodicalIF":1.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142587846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
