Title (EN) HYDROXY-FUNCTIONALIZED POLYESTER AND POLY(ESTER ETHER) OLIGOMERS
(FR) OLIGOMERES DE POLYESTER ET DE POLY(ESTER ETHER) HYDROXY-FONCTIONNALISES
Abstract: front page image
(EN)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.
(FR)Pour prépare des oligomères de polyester hydroxy-fonctionnels, on met en contact un acide dicarboxylique aliphatique hydroxy-fonctionnel, ou un mélange d'acides dicarboxyliques contenant des diacides aliphatiques hydroxy-fonctionnels, avec un éther ou un ester de diglycidyle en présence d'un catalyseur à base d'onium, dans un solvant à base d'éther, dans des conditions convenant pour former ledit oligomère. Ces oligomères peuvent être utilisés comme adhésifs thermofusibles, agents collants pour adhésifs, plastifiants, adhésifs thermodurcissables et revêtements thermodurcissables. Certains de ces matériaux étant biodégradables, ils peuvent être utilisés avec des produits finis compostables.
