A polyphenylene sulfide resin composition having excellent impact properties is provided which comprises:

Polyphenylene sulfide resin composition and a process for producing it

An antistatic resinours composition comprising (A) graft copolymers prepared by emulsion polymerization of (a) monomer mixture consisting of (i) from 50 to 100 percents by weight of monomers having polyalkylene oxide chains and (ii) from 50 to 0 percents by weight of vinyl monomers in the presence of rubbers and (B) thermoplastic resins compatible with the graft copolymers, has permanent antistatic performances, superior mechanical properties and high flowability.

Antistatic resinous compositions

A method is provided for continuously manufacturing high impact strength thermoplastic resins comprised of the sequential steps of (a) bulk-polymerizing a monomer solution, which contains a diene type rubber polymer or a graft polymer obtained by extracting the rubber polymer particle or vinyl monomer grafted polymer particle in latex with vinyl monomers which contain 5-20 percent by weight of water at a temperature of 85.degree.-135.degree.C, while continuously stirring the solution, vaporizing the volatile components, condensing the volatile component and recycling them back to reaction mixture, until the solid content in the reaction mixture reaches 40-75 percent by weight, and thereafter (b) bulk polymerizing the resulting prepolymer solution under the condition that plug-flowing can be attained with a temperature gradient 100.degree.-170.degree.C at the top of the reaction vessel and 170.degree.-270.degree.C at the bottom thereof, while the volatile component of the mixture are evaporated off, condensed and recycled to the reaction mixture, until the solid content is at least 90 percent by weight.

Method for producing impact resistant thermoplastic resin by continuous

High impact resistant thermoplastic resins are produced in three steps: (a) graft polymerizing a minor amount of unsaturated monomer onto a major amount of diene type rubber polymer in latex form, (b) mixing the grafted diene type rubber latex with a monomer or monomers, extracting the grafted rubber polymer particles into the monomer phase and separating and discarding the water phase to obtain a grafted rubber polymer particle dispersed monomer solution, and (c) bulk polymerizing the resulting rubber polymer particle dispersed monomer solution.
