A lot of ongoing experiments have expanded this chemistry, primarily with the chemical adjustments of the polymeric material. The chemical modification of PVC utilizing many materials as an active modifying agent is explained On this do the job. The latter comprised grafting polymerizations, nucleophilic radicals, substitutions, PVC modifications, and removal or dehydrochlorination. This perspective addresses the primary PVC reactivity developments and supplies an outline of PVC functionalization when inspecting the environmental implications of PVC by using the prism of chemical recycling. As a result of considerable ongoing research, this chemistry continues to be expanded, mainly with the chemical adjustments of this polymeric material. To boost its Picture-security Attributes, increase the programs of poly(vinyl chloride) (PVC), and examine PVC-relevant phenomena, quite a few chemical modifications are released to PVC.

اعتقاد بر این است که بیشتر محصولات وینیلی زمانی‌که به‌طور صحیح مصرف شوند عموماً بی‌ضررند هر چند تعدادی از افزودنی‌ها و نرم‌کننده‌ها از محصول وینیلی می‌توانند نشت کنند.
The contents on the response vessel are pressurized and frequently blended to maintain the suspension and make certain a uniform particle size شيش حصير from the PVC resin. The response is exothermic and so requires cooling. As the volume is lowered in the course of the response (PVC is denser than VCM), h2o is frequently added towards the mixture to keep up the suspension.[9]
