Star-bloc copolymers containing polycaprolactone and polylactide blocks of limited molecular weight are tough, easily degradable polymers. Such copolymers, which are noncrystalline and have glass transition temperatures near or below room temperature, are useful in many packaging and other applications.

Copolymères blocs en étoile contenant des blocs de polycaprolactone et de polylactide de poids moléculaire limité, qui sont solides et facilement dégradables. Ces polymères qui ne sont pas cristallins et présentent des températures de transition vitreuse proches de la température ambiante ou inférieures à cette dernière, sont utiles dans de nombreux emballages et dans d'autres applications.
