Moldings having improved surface properties are produced using BMC molding materials which contain crystalline unsaturated polyesters.

Molding ofBMC molding materials having improved surface properties

A curable molding material comprises a coherent phase of a free-radical curable, unsaturated polyester resin in which finely particulate polyolefin particles are dispersed as disperse phase, the two phases being chemically bound to one another at the interfaces by ionic bonds.

Curable molding material

A curable molding material based on a dispersion of a finely divided ethylene polymer in an unsaturated polyester resin is prepared by a process in which a melt of the ethylene polymer is uniformly distributed in a melt of an unsaturated polyester in an extruder or stirred kettle.

Preparation of a curable molding material

A heat-curable molding material consists of an unsaturated polyester, monomers, a propylene polymer, free radical initiators and conventional additives and assistants, the propylene polymer being dispersed in the form of solid, round particles having a smooth surface and a mean diameter of from 1 to 200 .mu.m in the polyester resin.

Heat-curable molding material

The invention relates to a curable, thickened molding material based on vinyl ester resins or vinyl ester urethane resins and containing a basic metal compound acting as thickening agent and also an acid group-containing thermoplastic vinyl polymer which is compatible with said resins.

Thickened, curable molding material based on a vinyl ester resin or a

A curable thickened polyester resin molding compound contains from 0.1 to 20 parts by weight of a thermoplastic vinyl polymer which is compatible with the resin and contains acid groups.

Thickened curable molding compound of unsaturated polyester resins

A thickened, uncrosslinked molding composition which has a long shelf life and can be cured above 50.degree. C. comprises a liquid reactive system, a thickener, a polymerization initiator and conventional additives. The thickener is a combination of a primary aromatic amine and an isocyanate. The molding compositions, which are, in particular, SMCs or BMCs, can be processed into moldings by compression molding, injection molding or transfer molding and subsequent curing.

Bismaleimides having the general formula ##STR1## in which n is a whole number between 5 and 70 and --X-- is --O-- or --NH-- are prepared through the reaction of the corresponding amino-terminated polyoxybutylenes with 2 moles of maleic anhydride. They are suited as toughening agents in high grade reactive resins.

Acylphosphine sulfides of the formula ##STR1## where R.sup.1 is alkyl, cycloalkyl or an unsubstituted or substituted phenyl, naphthyl or heterocyclic radical; R.sup.2 has the meaning of R.sup.1 and can be identical to or different from R.sup.1, or is alkoxy, unsubstituted or substituted phenoxy or phenoxyalkyl, or R.sup.1 or R.sup.2 are linked together to form a ring, which may contain further alkyl substituents and fused-on benzene rings; R.sup.3 is alkyl, a cycloaliphatic radical, substituted phenyl, an unsubstituted or substituted naphthyl or heterocyclic radical or the group ##STR2## where X is unsubstituted or substituted phenylene or an aliphatic or cycloaliphatic divalent radical; and where one or more of R.sup.1, R.sup.2 and R.sup.3 may be olefinically unsaturated.
