COPOLYMER OF LACTONE AND CARBONATE AND PROCESS FOR THE PREPARATION OF SUCH A COPOLYMER |
摘要 |
2126229 9313154 PCTABS00024 The invention relates to a copolymer of at least one lactone and at least one cyclic carbonate, the carbonate being polycyclic. This makes it possible to obtain cross-linked copolymers. The mechanical properties of objects obtained with these are considerably better than the mechanical properties of objects on the basis of non-cross-linked copolymers. The material is tough - in particular the tensile strength is higher -, impact resistant, less crystalline than non-cross-linked copolymer and it is biodegradable.
