Title (EN) LIQUID CRYSTAL COPOLYESTERS
(FR) COPOLYESTERS DE CRISTAUX LIQUIDES
Abstract:
(EN) Liquid crystal copolyesters having melting points low enough to allow the copolyesters to be melt-processed in conventional equipment. The copolyesters are prepared from terephthalic acid, 2,6-naphthalenedicarboxylic acid, a diacyl ester of hydroquinone and a diacyl ester of resorcinol and contain the following divalent radicals:
(FR) Des copolyesters de cristaux liquides ont des points de fusion assez bas pour permettre leur traitement par fusion avec une installation conventionnelle. Les copolyesters sont prepares a partir de l"acide terephtalique, de l"acide 2,6-naphthalenedicarboxylique, d"un ester diacyle d"hydroquinone et d"un diacyle ester de resorcinol et contiennent les radicaux bivalents suivants:
