Abstract: The invention relates to natural fatty acid based hybride resins, which have been modified with reactive monomers, such as acrylates, and especially to their use as binding agents and compatibilisators in combination products such as composites, as well as to composites containing them and to a method for the manufacture of the composites. The combination product comprises 1-50 weight-%, calculated from the dry matter, of a natural fatty acid based acrylate hybride resin, either as such or as an aqueous emulsion, and 99-50 weight-% of cellulose, wood, linen, hemp, starch or other natural fibre material or a combination thereof.

Abstract: The invention relates to acrylate modified, natural fatty acid based hybride polymers, and to a method for their preparation. The invention also relates to the use of the modified natural fatty acid based hybride polymers as binding agents especially in water based coatings, adhesives and composites and as environmentally friendly wood impregnating agents. The acrylate-modified natural fatty acid based hybride polymer is a block polymer formed of acrylate segments and fatty acid segments.
