Hydroxyl-terminated liquid polymers and process for preparation thereof.

摘要

Hydroxyl-terminated liquid polymers are prepared by reacting at least one aminoalcohol with a carboxyl-terminated liquid polymer having a carbon-carbon backbone. These polymers have better hydrolytic stability than hydroxyl-terminated liquid polymers containing ester groups, and are useful together with polyisocyanates for open or centrifugal casting, liquid injection molding and the like to produce various thermoset elastomeric products.
