The invention discloses composition, prepolymer and method to produce a polymer based on biodegradabler or essentially renewable crude materials,which can be crosslinked by free radicals. Composition is based on polyesters that are functionalised with unsaturated monomer units, in a way that unsaturated groups can be located along the polymer main chain as well as at the ends of the prepolymer. In connection to the product production, the prepolymer shall be exposed to free radicals that leads to network formation. The composition of the crosslinked biopolymer can be adjusted from a stiff engineering material to an elastic rubbery material. The new biopolymer can be used in composite materials, dispersions, barrier materials, rubbery materials, and in biomedical applications to mention a few possible application areas. |
