Vinyl polymer is a term used to describe a type of polymer derived from vinyl monomers. These monomers are compounds that contain a vinyl group, which is a type of chemical bond. There are several synonyms for the term vinyl polymer, including polyvinyl compound, vinyl compound, and vinyl copolymer. These terms refer to the same type of polymer, but may be used in different contexts or by different industries. Other synonyms include polyvinyl chloride (PVC), polyvinyl acetate (PVAc), and polyvinylidene chloride (PVDC). These synonyms are commonly used to refer to specific types of vinyl polymers, each with their own set of properties and uses.
