Claims
- 1. A process for producing a thermoplastic resin composition which comprises a thermoplastic resin and a modifier comprising a reaction product of (A) a styrene copolymer having a number average molecular weight of 1000 to 4000 and a copolymerization ratio of styrene to maleic anhydride of 1:1 to 5:1 in moles, with (B) poly(alkylene oxide) monoalkyl ether having a number average molecular weight of 100 to 5000, the amount of the modifier being 0.1 to 25% by weight based on the weight of the thermoplastic resin, which process comprises a step of melt-kneading the modifier with the thermoplastic resin.
- 2. A process for producing a rubber composition which comprises a rubber and a modifier comprising a reaction product of (A) a styrene copolymer having a number average molecular weight of 1000 to 4000 and a copolymerization ratio of styrene to maleic anhydride of 1:1 to 5:1 in moles, with (B) poly(alkylene oxide) monoalkyl ether having a number average molecular weight of 100 to 5000, the amount of the modifier being 0.1 to 25% by weight based on the weight of the rubber, which process comprises a step of melt-kneading the modifier with the rubber.
- 3. A process according to claim 1 wherein the thermoplastic resin is a homopolymer or copolymer of olefin or an olefinic polymer.
- 4. A process according to claim 1 wherein the thermoplastic resin is a homopolymer or copolymer of an alkyl ester of an unsaturated carboxylic acid.
- 5. A process according to claim 1 wherein the thermoplastic resin is a halogen-containing resin, a homopolymer or copolymer of styrenic monomers or a vinyl aromatic polymer.
- 6. A process according to claim 1 wherein the thermoplastic resin is polyphenylene ether, polyethylene terephthalate, polybutylene terephathalate, polyamide, polycarbonate, polyacetal, polysulfone, polyether sulfone, polyphenylene sulfide, polyarylate, polyphenylene ether/rubber modified polystyrene alloy, polyphenylene ether/polyamide alloy, polycarbonate/ABS alloy, polycarbonate/polybutylene terephthalate alloy, polypropylene/polyamide alloy, or polypropylene/polybutylene terephthalate alloy.
- 7. A process according to claim 2 wherein the rubber is natural rubbers, ethylene-.alpha.-olefin copolymer rubber, isoprene rubber, isoprene-isobutylene copolymer rubber, styrene-butadiene copolymer rubber, chloroprene rubber, epichlorohydrin rubber, or acrylonitrile-butadiene copolymer rubber.
