CONDOM

Abstract

The present invention provides a condom comprising a copolymer X obtainable by polymerisation of monomers A, B, C, and D; wherein monomer A is one or more compound of the formula: in which R1 and R2 are independently selected from H and C1-C20 alkyl optionally substituted by a hydroxyl, primary amine or secondary amine group, provided that one of R1 and R2 bears a hydroxyl, primary amine or secondary amine group; monomer B is one or more diisocyanate compound of the formula OCN-R3-NCO, in which R3 = C4-C20 alkylene, which may optionally be cyclic or branched; monomer C is one or more telechelic hydroxy terminated polyalkylene glycol compound having a number average molecular weight of 1000 to 10,000 and is preferably linear; monomer D is one or more diol of the formula HO-R4-OH, in which R4 is C2-C20 alkylene which may be interrupted by 1 – 5 heteroatoms selected from the group consisting of O, N and S, preferably 1 O atom and/or preferably wherein R4 is linear; wherein, the molar ratio of monomers D to C is in the range 0.1:1 to 10:1.
