FIELD: polymerization processes and catalysts.
SUBSTANCE: invention relates to catalytic system for (co)polymerization of lactide and glycolide and to (co)polymerization process using indicated system. Catalytic system is composed of (a) trifluoromethanesulfonate of general formula (1), (b) (co)polymerization additive of general formula (2), wherein molar ratio of additive to catalyst ranges from 0.05:1 to 5:1. (Co)polymerization process of lactide and glycolide is also described as well as application of thus obtained lactide and glycolide polymer or copolymer.
EFFECT: enabled controlling chain length, nature of end units of the chain of resulting (co)polymers.
