Abstract

the invention discloses a preparing method of quaternary polymer of acrylon-chlorinated polyethylene-triallylisocyanuric esters-styrene, which comprises the following steps: stirring to disperse 100wt% composition of acrylon, chlorinated polyethylene, triallylisocyanuric esters, styrene, 0.05-1.5wt% peroxide initiator, 0.5-4wt% organic / inorganic compound disperser, 0.05-0.5wt% emulsifier, 0-3.0wt% molecular weight adjuster and 200-500wt% deionized water; swelling under 20-50 deg.c for 0.5-2 h; polymerizing at 50-150 deg.c; stirring to polymerize for 4-10 h to obtain the product.

Description

technical field [0001] The invention relates to a preparation method of modified acrylonitrile---chlorinated polyethylene---styrene copolymer resin, especially a kind of acrylonitrile---chlorinated polyethylene---tripropenyl isocyanuric acid The invention relates to a preparation method of ester---styrene copolymer resin, which belongs to the field of organic chemical industry. Background technique [0002] The existing ABS resin (acrylonitrile --- polybutadiene --- styrene graft copolymer) is one of the most important and general-purpose engineering plastics, with excellent comprehensive physical --- mechanical properties, such as good Impact resistance, rigidity, toughness, etc., and good mechanical strength, electrical properties, and good processability, but butadiene in ABS contains double bonds, which makes it easy to oxidize and age in the air, thus making ABS poor in weather resistance and aging resistance. It is not suitable for outdoor use, and at the same time it...
