Abstract

During the production, storage, and use of polyvinyl chloride products, as a result of aging under the influence of ultraviolet rays, radiation, temperature, air oxygen, humidity, and other factors, HCl release, double bond formation, and oxidation are observed, along with certain disruptions in the macrochain. To prevent such phenomena, i.e., the use of low-molecular-weight stabilizing additives in the industry to stabilize polyvinyl chloride products, i.e., their high-molecular-weight counterparts instead of low-molecular-weight stabilizers, or the prolongation of the useful life of polymer products by chemically binding the same substances to the chain of the polyvinyl chloride macromolecule, can solve many economic problems of the consumer.
