    摘要： The invention relates to an unsaturated polyester resin mixture which can be cured by applying external pressure and which encompasses at least the following components: a) an unsaturated polyester resin whose weight-average molar mass is from 500 to 5000 g/mol; b) an ethylenically unsaturated monomer; c) a shrinkage-reducing component; d) an inert filler; and e) a reinforcing fibre; and f) from 0.01 to 1% by weight of a block copolymer, based on the total weight of the unsaturated polyester resin mixture comprising reinforcing fibre, where the block copolymer encompasses at least one A block and encompasses at least one B block, where the A block contains at least one amine-containing, ethylenically unsaturated monomer; and the B block contains at least one alkyl- and/or phenyl-containing, ethylenically unsaturated monomer, and is free from amine-containing, ethylenically unsaturated monomers. The present invention further relates to a process for preparation of the polyester resin mixtures and to the use of the block copolymers f) in unsaturated polyester resin mixtures.

    摘要： The present invention relates to processing aids for the processing of synthetic polymer compositions based on carboxylic esters, where the processing aids include, partial esters which contain at least 18 carbon atoms, have a number-average molecular weight of from 300 to 10,000, and can be prepared by the reaction of saturated or unsaturated aliphatic and/or cycloaliphatic polycarboxylic acids or anhydrides of these with saturated or unsaturated aliphatic, cycloaliphatic and/or aromatic monoepoxides and/or monoalcohols optionally containing ether groups, where at least 10% and not more than 90% of the carboxyl groups of the polycarboxylic acids have been reacted and the polycarboxylic acids and anhydrides of these contain from 8 to 100 carbon atoms. The invention further relates to the use of these processing aids in synthetic polymer compositions, and also to synthetic polymer compositions, which comprise these processing aids.
