Abstract

The invention relates to a polyvinyl chloride functional masterbatch, a functionalization method and application of the masterbatch. Specifically, the structure of the polyvinyl chloride functional masterbatch is shown as the specification. The invention solves the technical problem that existing PVC releases a lot of hydrogen chloride gas and other toxic gases under a high temperature effect. According to the invention, ferrocene is grafted to a PVC molecular chain through Friedel-Crafts reaction to replace the active chlorine on the PVC, thereby greatly improving the thermal stability of PVCand inhibiting the release of the hydrogen chloride gas. The thermal stability of PVC is improved, and the PVC is endowed with the redox reversibility function.

Description

technical field [0001] The invention relates to a polyvinyl chloride graft, in particular to a ferrocene functionalized polyvinyl chloride. Background technique [0002] PVC is a general-purpose plastic with a wide range of uses, and its output is second only to polyolefins. During the processing and application of PVC, because the molecular structure of polyvinyl chloride contains chlorine atoms, a large amount of hydrogen chloride gas and other toxic gases will be released under high temperature, which will cause huge damage to personnel and equipment. [0003] Since the accidental discovery of ferrocene by Kealy T J and Pauson P L in 1951, a major breakthrough has taken place in organic transition metal chemistry. Ferrocene, also known as dicyclopentadiene iron, is composed of two cyclopentadienyl anions and one Fe 2+ Organometallic compounds composed of ions [Fe 2+ (C 5 h 5 - ) 2 ], the molecule is electrically neutral, it is an electron-rich aromatic compound wit...
