Biodegradable multi-block co-polymers |
摘要 |
The invention relates to a biodegradable multi-block copolymer, comprising at least two hydrolysable segments derived from pre-polymers A and B, which segments are linked by a multi-functional chain-extender and are chosen from the pre-polymers A and B, and triblock copolymers ABA and BAB, wherein the multi-block copolymer is amorphous at physiological (body) conditions. The invention further relates to a process for preparing said copolymer and to its use as a medical implant, a coating for a medical device or a drug delivery vehicle.
