Abstract

A process for crosslinking a poly(alkylene carbonate) (PAC) in the presence of a metal ion, said process comprising: a) adding a crosslinking agent to said poly(alkylene carbonate) and b) crosslinking the resulting product of step a); so as to form a crosslinked PAC in which the crosslinks formed involve the complexation of the metal ion to said PAC and said crosslinking agent.
