Claims
- 1. A low gloss thermoplastic resin composition comprising a low gloss agent which comprises a grafted copolymer containing a low-cis polybutadiene having a Mooney viscosity of 30 to 40 measured at 100.degree. C. as a rubber component, 30% by volume or more of particles of the rubber component becoming non-spherical rubber particles when the low gloss agent is made into a molded article and at least one other polymer obtained by polymerization of an ethylenically unsaturated monomer and/or a polycarbonate.
- 2. A low gloss thermoplastic resin composition according to claim 1, wherein the other polymer is at least one member selected from the group consisting of an acrylonitrile-butadiene-styrene copolymer, methyl methacrylate-butadiene-styrene copolymer, acrylonitrile-ethylene propylene diene-styrene copolymer, acrylonitrile-butyl acrylate-styrene copolymer, acrylonitrile-butyl acrylate-.alpha.-methylstyrene copolymer and acrylonitrile-butyl acrylate-.alpha.-methylstyrene-N-phenyl-maleimide copolymer or is a vinyl chloride resin.
- 3. A low gloss thermoplastic resin composition according to claim 1, wherein the low gloss agent is used in an amount of 5% by weight or more.
- 4. A low gloss thermoplastic resin composition according to claim 1, wherein the low gloss agent is used in an amount of 30 to 70% by weight.
- 5. A heat-resistant low gloss thermoplastic resin composition according to claim 1, wherein the other polymer is a polycarbonate.
- 6. A heat-resistant low gloss thermoplastic resin composition according to claim 5, wherein the low gloss agent is used in an amount of 10 to 50% by weight.
- 7. A flame-retardant low gloss thermoplastic resin composition according to claim 1, wherein the other polymer is a vinyl chloride resin.
- 8. A flame-retardant low glass thermoplastic resin composition according to claim 7, wherein the low gloss agent is used in an amount of 20 to 70% by weight.
- 9. A low gloss thermoplastic resin composition according to claim 1, wherein the other polymer is a acrylonitrile-butadiene-styrene copolymer.
- 10. A low gloss thermoplastic resin composition according to claim 9, wherein the low gloss agent is contained in an amount of 5% by weight or more.
- 11. A composition according to claim 1, wherein the grafted copolymer is obtained by bulk polymerizing one or more monomers in the presence of a low-cis polybutadiene to a conversion of 1 to 15% by weight, and switching the bulk polymerization to suspension polymerization.
- 12. A composition according to claim 11, wherein the one or more monomers are at least one of aromatic vinyls and vinyl cyanides.
- 13. A composition according to claim 1, wherein the non-spherical rubber particles are dispersed in the molded article in the shape of fibers.
