Abstract
The present invention relates to a series of novel silicone polyesters which are prepared by crosslinking a dimethicone copolyol having at least 4 hydroxyl groups with a dimer acid. The ratio of acid groups to hydroxyl groups ranges from 0.7 to 1.4 so that a significant number of groups are reacted and a significant number of crosslink groups are achieved.
