Claims
- 1. A delustered thermoplastic resin composition obtained by incorporating in 100 parts by weight of a polyvinyl chloride, a cross-linked polymer in an amount, the minimum of which is sufficient to impart a significant delustering effect to said polyvinyl chloride, up to 40 parts by weight and having an average particle diameter of 35-500.mu. which polymer is obtained by suspension-polymerizing a non-cross-linking monomer composition comprising 50-70 wt. % of a vinyl aromatic monomer, 10-40 wt. % of at least one monomer selected from the group consisting of alkyl acrylates having 1-13 carbon atoms in the alkyl group, 10-40 wt. % of a monomer selected from alkyl methacrylates having 1-4 carbon atoms in the alkyl group and 0-40 wt. % of another mono-ethylenically unsaturated monomer with 0.5-5 parts by weight, per 100 parts by weight of the non-cross-linking monomer composition, of a cross-linking monomer having at least two double bonds in the molecule.
- 2. A delustered thermoplastic resin composition obtained by incorporating in 100 parts by weight of a from 5 parts by weight up to 40 parts by weight of a cross-linked polymer having an average particle diameter of 35-500.mu. which polymer is obtained by suspension-polymerizing a non-cross-linking monomer composition comprising 50-60 wt. % of a vinyl aromatic monomer, 20-30 wt. % of at least one monomer selected from the group consisting of alkyl acrylates having 1-13 carbon atoms in the alkyl group, 10-20 wt. % of a monomer selected from alkyl methacrylates having 1-4 carbon atoms in the alkyl group, and 0-10 wt. % of another monoethylenically unsaturated monomer with 1.5-4 parts by weight, per 100 parts by weight of the non-cross-linking monomer composition, of a cross-linking monomer having at least two double bonds in the molecule.
- 3. A delustered thermoplastic resin composition according to claim 1, wherein the crosslinking monomer is a compound containing at least one allyl group.
- 4. A delustered thermoplastic resin composition according to claim 2, wherein the crosslinking monomer is a compound containing at least one allyl group.
- 5. A delustered thermoplastic resin composition according to claim 1, wherein said alkyl acrylate is at least one member selected from the group consisting of ethyl acrylate, n-butyl acrylate and 2-ethylhexyl acrylate.
- 6. A delustered thermoplastic resin composition according to claim 2, wherein said alkyl acrylate is at least one member selected from the group consisting of ethyl acrylate, n-butyl acrylate and 2-ethylhexyl acrylate.
- 7. A delustered thermoplastic resin composition according to claim 1, wherein average particle diameter of the cross-linked polymer is 40-200.mu..
- 8. A delustered thermoplastic resin composition according to claim 2, wherein average particle diameter of the cross-linked polymer is 40-200.mu..
