Abstract
The present invention is directed to a novel internal release agent, a mixture of isocyanate reactive materials containing the release agent and a RIM process using the release agent. The novel release agent is a reaction product of 1) a polyester prepared by reacting (a) a polymerized fatty acid with (b) a relatively low molecular weight hydroxy group containing compound, and 2) a saturated monocarboxylic acid.
