What are PVC atoms?
Structurally, PVC is a vinyl polymer. (well, duh!) It’s similar to polyethylene, but on every other carbon in the backbone chain, one of the hydrogen atoms is replaced with a chlorine atom. It’s produced by the free radical polymerization of vinyl chloride.
What is PVC how it is prepared?
Poly Vinyl Chloride (PVC) is prepared by addition (chain growth) polymerisation of vinyl chloride. nCH2=Cl∣CH Peracid Pressure[−CH2−Cl∣CH−]n. Vinyl chloride Poly Vinyl Chloride (PVC) The monomer used is vinyl chloride (CH2=Cl∣CH). It is treated with peracid under pressure to obtain Poly Vinyl Chloride (PVC).
What are the types of PVC?
There are three broad classifications for rigid PVC compounds: Type I, Type II, and CPVC. Type II and CPVC offer better heat and chemical resistance as well as greater impact resistance. These materials are considered “unplasticized” (rigid) because they are less flexible than the plasticized formulations.
