    摘要: A bioresorbable polymer is obtained by reacting together (a) a prepolymer comprising co-polymerised units of a caprolactone and poly(alkylene oxide) moieties; (b) a polycaprolactone diol comprising co-polymerised units of a caprolactone and a C2-C6 diol; and (c) a diisocyanate. The polymer may be loaded with a pharmaceutically active agent to produce a drug delivery device.

    摘要: A water-swellable linear polyurethane polymer is formed by reacting a polyethylene oxide (e.g. PEG 4000 to 35,000), a difunctional compound (e.g. a diamine or diol such as 1,10-decanediol) with a diisocyanate. The ratio of the three components is generally in the range 0.1-1.5 to 1 to 1.1-2.5. The polyurethane is water-swellable in the range 300 to 1700% and soluble in certain organic solvents such as dichloromethane. It can be loaded with pharmaceutically active agents, particularly of high molecular weight, to produce controlled release compositions, such as pessaries etc.
