Abstract
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.
Claims7
A filled unsaturated polyester resin composition which comprises an unsaturated polyester resin, filler, and an effective amount of a substantially neutral lower alkoxylated alkyl acid phosphate composition for reduction of the viscosity of the composition wherein said alkyl acid phosphate contains a major amount of at least one compound of the formula ##STR2## where x is an integer of from 1 to 5, m and n are either 1 or 2, with the sum of m and n being 3, R is a C.sub.1 -C.sub.20 alkyl group and R' is a C.sub.2 -C.sub.5 alkylene group.
