Polyacrylate latex was synthesized via the emulsion polymerization technique. The polymer phase improves the hardness of brittle cement and provides stability due to the interactions between cement components and polymers. In this study, polymer latex [Methyl methacrylate (MMA), Stearyl acrylate (SA), Ethyl acrylate (EA)] was incorporated in cement paste with different weight proportions. Six samples of 50 mm × 50 mm × 150 mm size were prepared for testing. A hydration reaction was carried out to understand the interactions of polymer latex with cement paste. Subsequently, all samples were characterized and analyzed through Fourier transform infrared (FT-IR) spectroscopy, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), a compact pH meter, and morphology study via Scanning Electron Microscopy (SEM). The FTIR measurements confirmed polymer interaction with cement through changing intensity of -OH, C=O, and -COO^- peaks. The XPS investigation revealed a binding energy peak at 345.0 eV, confirming calcium formate formation. Results indicate that a cross-linked network structure is generated with Ca²⁺ as a cross-linker, enhancing the toughness of the polymer-cement composite. The improved composite properties, including reduced porosity, enhanced mechanical strength, and thermal stability, make it suitable for applications in construction materials such as bridges, dams, sewage systems, and infrastructure requiring durability and environmental resistance. This study highlights the potential of long-carbon chain polyacrylate latex to significantly enhance cement-based materials' performance.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"32 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995771","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}

Nanomedicine can help to easily deliver hydrophobic and hydrophilic agents for cancer treatment. Here, we describe a nanocarrier system that enables the sustainable and controllable release of hydrophobic anticancer drugs, Paclitaxel, based on poloxamer 407-conjugated gelatin (GeP) copolymers. The particle size, zeta potential, morphology, and thermal stability of the nanogels were characterized. The successful synthesis of nanogels was confirmed by analyzing their chemical components. Among the GePs at different amounts of poloxamer 407, a ratio of gelatin and poloxamer (Ge:P) at 1:15 for preparation resulted in the nanogels being positive in charge, spherical in shape, and 97.84 ± 2.94 nm in hydrodynamic diameter (Dh), with optimal drug-carrying efficacy. The in vitro drug release from nanogels was accelerated in the tumor microenvironment at pH 5.5 in comparison to pH 7.4, and the drug release kinetics from nanogels were due to Fickian diffusion. Finally, the cytotoxicity assays indicated that GePs were biocompatible nanocarriers without toxicity on both normal (VERO) and breast cancer cell (MCF-7) lines, which could improve the pharmacokinetics and pharmacodynamics of paclitaxel. Overall, these results revealed an optimal ratio (1:15) of Ge:P for the synthesis of pH-responsive hybrid nanogels for sufficient paclitaxel releasement to kill MCF-7 for effective cancer treatment.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"32 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10965-024-04248-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142995575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the chemical modification of chitosan via graft copolymerization with vinyl monomers (methacrylamide and tert-butyl acrylate) in an aqueous medium using ceric ammonium nitrate as an initiator. Three varieties of chitosan and grafted chitosan (10–30%) were combined with low-density polyethylene at various ratios via a twin-screw extruder. To enhance the interfacial interaction between the two materials, maleic anhydride was grafted onto low-density polyethylene and employed as a compatibilizer (5 and 10%). The grafted chitosan was analyzed via fourier transform infrared spectroscopy, gel permeation chromatography, and grafting parameters, such as the percentage of grafting G (%), efficiency E (%), and yield of grafted copolymerization Y (%), were determined. The polymeric blends were produced by twin screw extruder and automatic injection molding machine and subsequently evaluated for their mechanical properties, scanning electron microscopy, thermogravimetric analysis, chemical resistance, and biodegradation studies.
