23443-495 ABSTRACT A mould for the production of latex foam mouldings by means of microwave heating is disclosed. The mould has passivated surface and walls made of a moulding composition comprising from about 20 to about 100 parts by weight of a polyphenylene ether composed of units of the formula Image in which R1 and R2 represent an n-alkyl group having up to 6 carbon atoms, or R1 denotes hydrogen and R2 denotes a tertiary alkyl radical having up to 6 carbon atoms; and R3 and R4, independently of one another, represent a methyl group or hydrogen. The moulding composition may further comprise from 0 to 80 parts by weight of styrene polymers, 0 to 30 parts by weight of impact-modifying additives, 0 to 40 parts by weight of reinforcing agents and/or fillers and 0 to 15 parts by weight of additives. When used for moulding of latex foams, the moulds according to the invention ensure an easy release and a good dimensional stability of mouldings, as well as a long serviceable life. Compared with known processes of production of latex foam mouldings, the process using the mould of invention is character- ized by a reduced cycle time and energy consumption.
