The present invention provides a biocompatible polymer composition for use in biomedical applications comprising a base molecule, a linker molecule and at least one initiator compound, said base molecule having at least two differing functionalities, and said linker molecule having a functionality reactive with at least one functionality of said base molecule, the first of said at least two functionalities of said base molecule enabling a first curing stage of said polymer composition by reaction with said linker molecule, and the second and any further functionality of said base molecule enabling second and further curing stages of said polymer composition, said first, second and any further curing stages being capable of activation simultaneously or independently of each other as required.

Biocompatible polymer compositions for dual or multi staged curing

The present invention provides a biocompatible prepolymer comprising hydrophilic and hydrophobic segments, wherein the hydrophobic segments have at least one ethylenically unsaturated functional group and at least 5% of the segments have two or more ethylenically unsaturated functional groups and water. The invention further provides a biocompatible prepolymer composition comprising hydrophilic and hydrophobic prepolymers, wherein at least one of the hydrophobic prepolymers has at least one ethylenically unsaturated functional group and at least 5% of the prepolymers have two or more ethylenically unsaturated functional groups and water. The invention further provides use of the prepolymer or prepolymer compositions of the invention in biomedical applications such as tissue engineering, as bone substitutes or scaffolds, and in wound treatment.

Biocompatible polymer compositions

The instant invention discloses a process for the preparation a polyolefin nanocomposite which comprises melt mixing a mixture of a polyolefin, a filler and a non-ionic surfactant.

Process for the preparation of polyolefin nanocamposites

The instant invention discloses a composition, preferably a nanocomposite material, comprising (a) a synthetic polymer, (b) a filler selected from a natural or synthetic phyllosilicate or a mixture of such phyllosilicates, preferably in nanoparticles, and (c) a dispersing agent prepared by controlled free radical polymerization (CFRP).

Dispersing agents in nanocomposites

The instant invention discloses a composition, preferably a nanocomposite material, comprising (a) a synthetic polymer, (b) a filler such as for example a natural or synthetic phyllosilicate or a mixture of such phyllosilicates, preferably in nanoparticles, and (c) as dispersing agent a polymer based on a long chain alkyl meth(acryte).
