The compound mixture of one or both of carbonic acid bis- (2- ethylhexyls), the new certain herbaceous plants with big flowers acid esters of dicumyl peroxide.
14. a kind of chloroethylene copolymer resin as claimed in claim 3, it is characterized in that, first pH adjusting agent is carbonic acid
One kind in hydrogen sodium, ammonium hydrogen carbonate, sodium hydroxide, ammonium hydroxide.
15. a kind of preparation method of chloroethylene copolymer resin as described in claim 1, it is characterized in that, include the following steps：
Deionized water, pH adjusting agent and dispersant are added in reaction vessel, 5~10min is mixed, adjust pH value for 7.0~
8.0, be subsequently added into acrylate nano rubber latex and polymerization initiator, 5~10min be mixed, and add in vinyl chloride monomer and
Simultaneously 10~15min is mixed in hydroxyl monomer；Then reaction system is warming up to 55.5~57.5 DEG C, adjusts reaction system pressure
Power is 0.85~0.95MPa, and aggregated reaction adds in terminator and terminate when pressure drop reaches 0.1MPa in reaction vessel
Reaction, after reaction product removes residual vinyl chloride, by centrifuging, drying to get chloroethylene copolymer resin.
