The residual emulsifier in PVC products brings some undesirable issues when it is used in some special application scenarios. Soap-free emulsion polymerization technology provides a strategy to reduce the possible environmental pollution caused by emulsifier residue. Very recently, we have developed a soap-free emulsion polymerization system for PVC based on the ternary copolymerization between vinyl chloride, vinyl acetate, and maleamic acid ammonium salt. Herein, we mainly investigate the effect of VCM soap-free emulsion polymerization from five aspects: ionic strength, initiator dosage, monomer concentration, reaction temperature, and stirring speed. Suitable ionic strength is the key to maintaining the stability of the soap-free system. The initiator dosage, reaction temperature, and monomer concentration are important means to control the reaction rate, number-averaged molecular weight (M\u0000 n), and particle size. Increasing the stirring speed can accelerate the reaction rate. By tuning the above conditions, PVC latex particles with a particle size of 123–272 nm and M\u0000 n of 54,000–139,800 g/mol can be prepared.

However, in industrial applications, the importance of the molecular chemical composition of the EVA in the emulsions is often neglected.

Several qualified solvents have been identified. Here, we comparatively study the effects of solvents on piezoelectric performance and production yield, for choosing the right solvent for fully solution-processed multilayer piezoelectric devices. Each solvent exhibits distinct yield dependence on drying temperature, but the maximal yields achieved are independent of processing solvents. The solvents are also found to be interchangeable in terms of piezoelectric performance. The drying temperature and final annealing temperatures are identified to be decisive factors. The former only impacts the yield, and the latter only impacts the performance. The three parameters that define a poling condition are all investigated for the first time. A procedure enabling a fast identification of the right poling condition is proposed. Fully solution-processed P(VDF-TrFE) multilayer piezoelectric devices are prepared using the optimized conditions, and the dependence of the performance and yield on the number of layers is demonstrated.

The inherently stable nature of silicone elastomers gives them unique properties, but complicates their reentry to a circular material loop. This paper presents a recyclable silicone elastomer with crosslinks constituted by silyl ethers. Condensation curing of carbinol-functional polydimethylsiloxane (PDMS) with polysilazane (PSz) is proven to create a stable silicone elastomer without the need for a metal catalyst. The mechanical properties can be easily tuned by the addition of fillers as well as by chain extension. Adding the cured silicone elastomer to a solution of 0.055 mol L−1 acetic acid (AcOH) in tetrahydrofuran (THF) for 24 h at 40°C yields a liquid silicone with a high resemblance to the starting polymer, demonstrating a selective cleavage of the silyl ether crosslinks. Experiments show that this reclaimed silicone can successfully be recured using new PSz to form new silicone elastomers. Mechanical properties similar to the starting elastomer are achieved when the reclaimed silicone is cured with pristine polymer in a 1:1 ratio, demonstrating the potential for industrial applications, where cured production scrap could be reintroduced to new elastomers via a simple process.","PeriodicalId":16888,"journal":{"name":"Journal of Polymer Science","volume":"63 14","pages":"2891-2902"},"PeriodicalIF":3.9,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pol.20250282","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the molecular modeling of polyethylene is still not fully developed, the simulated systems often involve relatively low molecular weights and single components, and it cannot be well combined with the experiment to study the mechanical properties of UHMWPE/HDPE blends. Therefore, this paper combined experimental analysis with simulations to investigate the flow modification and tensile properties of UHMWPE/HDPE blends and established a semicrystalline UHMWPE/HDPE model. The result shows that the flow modification effect of HDPE is more pronounced at lower screw rotational speeds, and the UHMWPE/HDPE mass ratios of 6/4 and 5/5 can produce as-spun filaments with better surface quality at a screw speed of 5 r/min. As the HDPE content increases, the blends' molecular chain mobility and disentanglement capability improve. However, an excessively high HDPE content hinders the enhancement of blend orientation.
