Description

technical field

[0001] The invention relates to the field of vinyl chloride resin synthesis, in particular to a rigid vinyl chloride copolymer, a preparation method thereof, a composition comprising the same and a resin product made from the composition. Background technique

[0002] Polyvinyl chloride (PVC) resin is formed by free radical polymerization of vinyl chloride monomer (VC). It is one of the five general-purpose resins in synthetic materials. Its output is second only to polyethylene and polypropylene, ranking third in the world for general-purpose plastics. . Due to its excellent chemical resistance, chemical stability, thermoplasticity and low manufacturing cost, PVC resin is widely used in construction, water supply, daily use and biomedical fields.

[0003] Due to the relatively large polarity of the PVC molecular chain, the movement of the molecular chain is restricted, which increases the processing difficulty of PVC resin. Therefore, plasticizers should b...
