CPVC chlorinated method is aqueous suspension (slurry) chlorided. Under the certain conditions using the special-purpose PVC resin and the chloride ion Carried on the permutation reaction to obtain the corresponding model CPVC resin. its molecular structure is: - CHCl-CHCl-CH2-CHCl-
Because chlorinity increase, CPVC molecular not neat increases (crystallinity in the structure to drop, molecular chain's polar enhancement), thus causes its thermal deformation temperature rise. The CPVC product's application temperature may reach 93-100℃, compares the PVC enhancement 30-40℃.
