PVC was discovered twice in the 19th century, one in Henry Victor Regnault in 1835 and the other in 1872 by Eugen Baumann. In both opportunities, the polymer appeared in a beaker of vinyl chloride placed under the sun as a white solid.

Industrial production of PVC molecular weight is generally in the range of 50,000 to 110,000, with greater polydispersity, molecular weight increases with the decrease of polymerization temperature; no fixed melting point, 80-85 ° C begins to soften, 130 ° C becomes viscoelastic state , 160 ~ 180 ° C began to transform into a viscous flow state; has good mechanical properties, tensile strength of about 60MPa, impact strength of 5 ~ 10kJ / m2; has excellent dielectric properties.
The investment required for the production of PVC is large, the fixed cost is high, and the scale benefits are obvious. Large-scale enterprises are in a more favorable position in negotiating with suppliers, which is conducive to reducing raw material costs. Enterprises with large production and sales have a higher market share, have greater market influence, and are relatively easier to obtain customers. Once the production and sales of PVC production enterprises reach a large scale, the marginal cost will be gradually reduced and the ability to resist risks will be enhanced.
