Lactone copolymers are disclosed which are polymerized from a first lactone monomer and a second amorphous monomer which is effective to suppress the crystallization of the copolymer. It is disclosed that suppression of the crystallization can provide enhanced mechanical properties in films made from the copolymers. As a result, films prepared from the copolymers of the present invention can have properties rendering them suitable for use as biodegradable trash bags as well as for other uses.
Cette invention se rapporte à des copolymères de lactone qui sont polymérisés à partir d'un premier monomère de lactone et d'un second monomère amorphe qui supprime efficacement la cristallisation du copolymère. On a découvert que la suppression de la cristallisation permet d'améliorer les caractéristiques mécaniques de films fabriqués à partir de tels copolymères. Par conséquent, les films fabriqués à partir des copolymères de la présente invention peuvent présenter des caractéristiques qui en font des copolymères adaptés à la fabrication de sacs à ordures ménagères, biodégradables, ainsi qu'à d'autres applications.
