Polyvinyl chloride (alternatively: poly (vinyl chloride), [6][7] colloquial: vinyl[8] or polyvinyl; abbreviated: PVC[8]) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. [9]

2024年11月27日 · Poly (vinyl chloride) (PVC) has been a fascinating subject for polymer science research. Its characteristics are heightened by its inherent structural faults resulting from direct manufacturing (by free-radical polymerization), which also cause its thermal instability.

2021年9月24日 · Polymerization of vinyl chloride takes place by a free radical addition process, comprising four elementary reactions: initiation, propagation, chain transfer to monomer and bimolecular termination steps. PVC resin can be produced by the following mostly used methods: solution, bulk, emulsion and suspension polymerization.

2018年5月1日 · New ternary nanocomposite systems containing polylvinyl chloride (PVC), chitosan modified ZnO (CMZN) nanoparticles and new synthesized polyamide (PA) were designed and prepared by solution casting method. As a potential reinforcement, CMZN was used in PVC system combined with and without PA.

2023年12月19日 · 聚氯乙烯（Polyvinyl chloride)，英文简称PVC，是 氯乙烯单体 （VCM）在过氧化物、偶氮化合物等引发剂或在光、热作用下按 自由基聚合反应 机理聚合而成的聚合物。氯乙烯均聚物和氯乙烯共聚物统称之为氯乙烯树脂。

2021年9月24日 · Polyvinylchloride (PVC) is one of the widely used synthetic polymers which can be used in many industries like packaging, automobiles, electrical, medical, sports and construction. It can be prepared by different polymerization techniques.

2022年12月19日 · Polyvinyl Chloride (PVC or Vinyl) is a high-strength thermoplastic material. It is widely used in applications such as pipes, medical devices, and wire & cable insulation...the list is endless. It is the world's third-most widely produced synthetic plastic polymer. So, what is PVC? What is it made up of? How to process it?
