Title (EN) COPOLYESTERS OF POLYBUTYLENE TEREPHTHALATE
(FR) COPOLYESTERS DE TEREPHTHALATE DE POLYBUTYLENE
Abstract: front page image
(EN)Novel thermoplastic copolyesters useful in fibers, films and molding resins are prepared by the transesterification of (a) straight or branched chain poly(1,4-butylene terephthalates) and (b) a polyester of (i) a cycloaliphatic 1,2-dicarboxylic acid or a derivative thereof, etc., and (ii) 1,4-butanediol. Compositions comprising the new copolymers with high molecular weight poly(1,4-butylene terephthalates) and with reinforcing agents are also disclosed.
(FR)Des nouveaux copolyesters thermoplastiques utiles dans les fibres, films et resines de moulage sont prepares par transesterification de (a) une chaine droite ou ramifiee de poly (1,4-terephthalates de butylene) et (b) un polyester de (i) un acide 1,2-dicarboxylique cycloaliphatique ou un derive de cet acide, etc, et (ii) de 1,4-butanediol. Des compositions comprenant les nouveaux copolymeres avec des poly(1,4-terephthalates de butylene) de poids moleculaire eleve et avec des agents de renforcement sont egalement decrites.
