Abstract
Heat-hardenable moulding compositions of: A. from 3 to 30 parts by weight of a thermoplastic polymer, B. from 20 to 70 parts by weight of a copolymerizable vinyl compound, and C. from 20 to 70 parts by weight of a polyesterurethane containing .alpha.,.beta.-unsaturated dicarboxylic acid radicals.
Claims6
A heat hardenable moulding composition which is a blend of preformed ingredients comprising
- a. from 3 to 30 parts by weight of a thermoplastic polymer having a molecular weight of 500 to 10,000,000,
- b. from 20 to 70 parts by weight of a copolymerizable vinyl compound,
- c. from 20 to 70 parts by weight of a polyesterurethane having .alpha., .beta.-ethylenically unsaturated dicarboxylic acid residues and a urethane group equivalent of at least 0.05 equivalents per 100 g. of polyesterurethane and
- d. a viscosity-increasing amount of a member selected from the group consisting of oxides and hydroxides of the metals of Group IIa of the Periodic Table.
