Title (EN) FOAMABLE COPOLYESTERS
(FR) COPOLYESTERS EXPANSIBLES
Abstract: front page image
(EN)Disclosed are foamable copolyester compositions containing 0.5 to 5.0 mole percent of a dicarboxylic acid sulfomonomer which contains at least one metal sulfonate group attached to an aromatic nucleus. These copolyesters possess high melt viscosity and are readily foamable with a wide range of foaming agents to provide low density shaped articles, films, and sheets.
(FR)L'invention se rapporte à des compositions de copolyester expansibles contenant un pourcentage molaire de 0,5 à 5,0 d'un sulfomonomère d'acide dicarboxylique renfermant au moins un groupe sulfonate métallique accolé à un noyau aromatique. Ces copolyesters possèdent une viscosité élevée en fusion et sont aisément expansibles à l'aide d'une grande variété d'agents gonflants, pour former des feuilles, films et articles profilés à basse densité.
