Abstract
A composition, prepolymer and method to produce a polymer based on biodegradable or essentially renewable crude materials, which can be crosslinked by free radicals. The composition is based on polyesters that are functionalized 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 is 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, biomedical applications, and the like.
