Today's pipe made of polyvinyl chloride (PVC) is used as basic good in different industries. The thermal stability of the PVC while is filled with ZnO nanoparticles was studied in this paper. This paper show that the stability of the PVC resin mixed with ZnO nanoparticles solution and Sn was better than that of the PVC resin mixed with Sn alone. The UV (ultraviolet)–vis spectra is showed that under certain heat treatment conditions, the PVC samples without ZnO nanoparticles solution embodied relatively high content of the conjugated double bonds with the chain length of about 3–5. However, the content of the conjugated double bond with the chain length of about 6 was greatly increased when the nanoparticles was filled into the PVC resin. This work shows the ZnO nanoparticles could inhibit the thermal degradation process of PVC resin in ionic mechanism.

Compounds based on polyvinylchloride plasticate containing a complex stabilizer based on salts of calcium and zinc stearates were obtained. The thermal properties of the obtained compounds are investigated. It was found that the introduction of a complex stabilizer in PVC compound leads to increased thermal stability of the compound. It is shown that the complex stabilizer affects the destructive processes that occur in the polymer matrix at elevated temperatures. It was found that the introduction of a complex stabilizer based on a mixture of calcium and zinc stearates in polyvinyl chloride plastics results in materials with improved processability.

Here, we synthesized a series of polymeric thermal stabilizers for polyvinyl chloride (PVC) based on maleic anhydride derivatives, including N-phenylmaleimide (NPMI), N-p-chlorophenyl maleimide (NCIPMI), N-p-nitrophenyl maleimide (NNOPMI), dibutyltin maleate (DBTM) and dioctyltin maleate (DOTM). Five specimens were prepared by mixing and rolling through a blending machine and a double-roller mixer, respectively. These samples were first subjected to thermal degradation in a 180°C hot oven, and fractions were collected every 10 min, followed by spotting on a slip of test paper. From the degree of color change in the test paper, the influences of these compounds on the thermal stability of PVC were estimated and such mechanisms were also discussed.
