FILLED UNSATURATED POLYESTER RESIN COMPOSITIONS

摘要

The viscosity of filled unsaturated polyester resin compositions is reduced by the incorporation in said compositions of an effective amount of a composition comprising a lower alkoxylated alkyl acid phosphate ester. The alkyl acid phosphate contains a major amount of at least one compound of the formula wherein x is an integer of 1 to 5, m and n are either 1 or 2 with their sum being 3, R is a C1-C20 alkyl group and R' is a C2-C5 alkylene group. The polyester resin compositions having lower viscosities are more processable.
