Title:
HYDROXY-FUNCTIONALIZED POLYESTER AND POLY(ESTER ETHER) OLIGOMERS
Document Type and Number:
WIPO Patent Application WO1998051728
Kind Code:
A3
Abstract:
Hydroxy-functional polyester oligomers are prepared by contacting a hydroxy-functional aliphatic dicarboxylic acid or a mixture of dicarboxylic acids containing hydroxy-functional aliphatic diacids, with a diglycidyl ether or diglycidyl ester in the presence of an onium catalyst in an ether solvent under conditions suitable for forming the oligomer. The oligomers can be used as hot-melt adhesives, adhesive tackifiers, plasticizers, heat-curable adhesives and heat-curable coatings. Some of these materials are biodegradable and are therefore suitable for application to compostable end products.
