Abstract
A composition suitable for preparing a biodegradable implant, comprising a crosslinkable multifunctional prepolymer having at least two polymerizable end groups, the said composition having a viscosity such that it is deformable at a temperature of 0° to 60° C. into a three-dimensional shape and being crosslinkable within the said temperature range. The prepolymer comprises a hydrophilic region and/or the composition further comprises an effective amount of a mineral biologically-active component delivery system and/or a biocompatible degradable porosity-inducing component.
