The invention relates to a polyvinyl chloride processing modifier capable of improving fusant strength, a preparation method thereof and polyvinyl chloride modified by the same. The conventional polyvinyl chloride (PVC) modifier cannot improve the fusant strength of the modified polyvinyl chloride effectively, the several known PVC modifiers capable of improving the fusant strength have to be used in a large amount with poor effect, so the cost of modified polyvinyl chloride products is increased objectively. For solving this problem, a macromoleclar polymer is obtained by copolymerizing 70 to 100 weight parts of alkyl methacrylate and 0 to 30 weight parts of alkyl acrylate in chloroform serving as a solvent, wherein by measuring at the temperature of 25+/-0.1 DEG C, the intrinsic viscosity of the macromoleclar polymer is between 13.2 and 16. The invention also discloses a preparation method of the polyvinyl chloride processing modifier capable of improving the fusant strength and the products ...

Принадлежит:

The invention relates to an efficient polyvinyl chloride (PVC) modifier with good thermal stability and shock resistance and PVC modified by the efficient polyvinyl chloride modifier. The existing PVC modifier has the advantages of poor thermal stability and shock resistance, large dosage and lower ultraviolet resistance. Therefore, the monomer polymer of the PVC modifier in the invention comprises the following components in parts by weight: 60-80 parts of styrene monomer, 10-30 parts of acrylonitrile monomer and 0-10 parts of alkyl acrylate. The preparation method of the PVC modifier adopts a two-stage reaction, a material is dropped in the second stage reaction; and when the obtained PVC processing modifier is measured at 25+/-0.1 DEG C by using chloroform as the solvent, the intrinsic viscosity is 3.5-4.5. The invention also relates to the corresponding modified PVC. The PVC modifier in the invention has the advantages of good thermal stability and shock resistance and also has dosage ...
