Title (EN) COMPOSITIONS COMPRISING CRYSTALLINE CONDENSATION POLYMERS AND NUCLEATING AGENTS
(FR) COMPOSITIONS COMPRENANT DES POLYCONDENSATS CRISTALLINS ET DES AGENTS NUCLEANTS
Abstract: front page image
(EN)Compositions comprising crystalline condensation polymers, e.g., polycaprolactone, and nucleating agents are disclosed. The compositions are suitable for use, for example, in preparing extruded or molded articles, such as, biodegradable films, implantable medical devices, sheets, planting containers and fibers. Preferably, the nucleating agents are compounds having a heterocyclic group containing about 4-6 carbon atoms. Vitamin E is disclosed as being particularly useful as a nucleating agents.
(FR)L'invention concerne des compositions comprenant des polycondensats cristallins, par exemple une polycaprolactone, ainsi que des agents nucléants. Ces compositions sont conçues, par exemple, pour préparer des articles extrudés ou moulés, tels que des films biodégradables, des dispositifs médicaux implantables, des feuilles, des contenants de plantation et des fibres. De préférence, les agents nucléants sont des composés possédant un groupe hétérocyclique contenant environ 4 à 6 atomes de carbone. L'invention décrit encore la vitamine E comme étant notamment utile en tant qu'agent nucléant.
