摘要： The invention relates to a method of manufacture of a thermoset polymer foam that is at least from 50 to 100 percent by weight of renewable raw material resources and to the foam obtained by the method. Foam is obtained from a two-component system that cures at room temperature after mixing in the presence of a strong base catalyst by carbon-Michael addition polymerization, forming mechanically rigid and highly cross-linked polymer. Both components of the carbon-Michael addition are developed from bio-based feedstock.
