Abstract

The invention relates to the technical field of vinyl chloride-butyl acrylate copolymer resin and particularly relates to vinyl chloride-butyl acrylate copolymer resin with ultralow polymerization degree and a preparation method thereof. The vinyl chloride-butyl acrylate copolymer resin with ultralow polymerization degree is prepared from the following raw materials: desalted water, a vinyl chloride monomer, a compound dispersant, a compound initiator, chain transfer agent mercaptoethanol and butyl acrylate. According to the vinyl chloride-butyl acrylate copolymer resin, acrylate is used as amain body; the vinyl chloride monomer is introduced; mercaptoethanol is used as the chain transfer agent of polymerization reaction; acrylate, the vinyl chloride monomer and the mercaptoethanol are copolymerized with the compound dispersant and the compound initiator to obtain the vinyl chloride-butyl acrylate copolymer resin with ultralow polymerization degree. Compared with the conventional chloroacylic resin and PVC resin, the vinyl chloride-butyl acrylate copolymer resin with ultralow polymerization degree has the advantages of low polymerization degree, high apparent density, low viscosity, regular particle shape and high resin flowability; meanwhile, the vinyl chloride-butyl acrylate copolymer resin is short in plasticizing time and easier to shape and process, and has more extensiveapplication fields in subsequent processing and application.

Description

technical field [0001] The invention relates to the technical field of vinyl chloride-butyl acrylate copolymer resin, and relates to an ultra-low degree of polymerization vinyl chloride-butyl acrylate copolymer resin and a preparation method thereof. Background technique [0002] Chlorine propylene resin is a new type of PVC processing aid, which is mainly composed of acrylate and introduced vinyl chloride monomer. It has similar solubility parameters to PVC resin, has excellent compatibility and blending performance, low processing melting point temperature, low melt viscosity, good internal plasticizing effect, reduces the amount of plasticizer, and contains carbon base in the structure. It can increase the light transmittance of the film, improve the impact strength of the product, low temperature flexibility, surface gloss, light resistance and anti-aging properties. It can be widely used in the molding and processing of hard and soft PVC products, and is an updated pro...
