TOMPosite

Project description

The main objective of TOMPosite project is to develop a thermoset two-component polymer resin with different crosslinking densities, suitable for developing composites with natural origin fibers, and reaching high (up to 90%) renewable material content and competitive characteristics. Pulp production side stream tall oil fatty acids (TOFA) and Meldrum’s acid synthesized from renewables will be utilized to synthesize the main components for polymer resin. The Michael nucleophilic addition will be exploited as a curing reaction for polymer matrix development. Two types of Michael donors will be synthesized by: converting TOFA-based polyols into acetoacetate by transesterification; cleavage of a Meldrum`s acid derivative with TOFA-based polyol. Two types of Michael acceptors will be obtained: by acrylation of TOFA-based polyols with acryloyl chloride; from epoxidized TOFA and TOFA-based fatty alcohol ester by oxirane ring opening with acrylic acid. Composites will be developed with reinforcement of natural origin short fibers and fabric.
