Title: CARBOXYLATED NITRILE BUTADIENE RUBBER GRAFTED POLYPHENYLENE SULFIDE RESIN AND SYNTHETIC METHOD THEREFOR
Abstract:
The present invention discloses a carboxylated nitrile butadiene rubber grafted polyphenylene sulfide resin, mainly prepared by a polymerization reaction of sodium sulfide, p-dichlorobenzene, lithium chloride, and carboxylated nitrile butadiene rubber. Further provided is a synthetic method for a carboxylated nitrile butadiene rubber grafted polyphenylene sulfide resin, comprising a dehydration processing process of sodium sulfide, a prepolymerization and polycondensation reaction process, a dehydration process of carboxylated nitrile butadiene rubber, a grafting and cross-linking process of the carboxylated nitrile butadiene rubber and a polyphenylene sulfide ether, and a discharging and washing process. The carboxylated nitrile butadiene rubber grafted polyphenylene sulfide resin of the present invention has an impact strength 20% to 50% higher than the impact strength of a polyphenylene sulfide that is not grafted with carboxylated nitrile butadiene rubber.
