Claims
- 1. Elastic-thermoplastic and thermoplastic powder-form moulding composition produced by the process which comprises
- providing a latex of a moulding composition containing from 0.75 to 10 parts by weight, based on 100 parts by weight of latex solids, of a thio group-containing elastic-thermoplastic graft polymer in emulsion form comprising thermoplastic resin forming monomers grafted onto a rubber wherein the thermoplastic component has a Vicat A/120 softening temperature of from 30.degree. to 95.degree. C. and a sulphur content of 0.5 to 5.0% by weight as thioalkyl groups
- and precipitating the moulding composition mixture by addition of coagulating agents at from 75.degree. to 120.degree. C. and recovering the polymer mixture.
- 2. Composition according to claim 1 wherein from 1 to 8 parts by weight of sulphur containing thermoplastic graft polymer is used.
- 3. Composition according to claim 1, wherein the sulphur content is from 0.8 to 3.5% by weight.
- 4. Composition according to claim 1 wherein the sulphur-containing elastic-thermoplastic graft polymer is a reaction product of styrene, .alpha.-methylstyrene, p-methylstyrene, vinyl toluene, (meth)acrylonitrile, methyl(meth)acrylate, N-phenyl maleic imide or a mixture thereof and a mercapto group-containing compound in the presence of a rubber having a glass transition temperature of <10.degree. C.
- 5. Composition according to claim 1 wherein the sulphur-containing elastic-thermoplastic graft polymer is a reaction product of:
- (a) from 50 to 80 parts by weight of styrene and/or .alpha.-methylstyrene:
- (b) from 10 to 30 parts by weight of acrylonitrile: and
- (c) from 7.5 to 25 parts by weight of t-dodecyl mercaptan; on
- (d) from 10 to 200 parts by weight of polybutadiene.
