POLYESTER AND POLY(ETHERO-ESTER) OLIGOMERS WITH HYDROXYLIC FUNCTIONAL GROUPS
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...

Summary: | 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. |
