维基百科的解释
Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated
PVC, is the third-most widely produced synthetic
plastic polymer, after
polyethylene and
polypropylene.
[4]
PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in
construction for pipe and in profile applications such as doors and windows. It is also used for bottles, other non-food packaging, and cards (such as bank or membership cards). It can be made softer and more flexible by the addition of
plasticizers, the most widely used being
phthalates. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, signage, inflatable products, and many applications where it replaces rubber.

Pure poly(vinyl chloride) is a white, brittle solid. It is insoluble in alcohol but slightly soluble in
tetrahydrofuran.
