Process for the preparation of polyaddition products of isocyanates and denatured biomasses, their use as reactive fillers and as plant nutrients and a process for the production of sheets or shaped articles using the polyaddition products

摘要

The instant invention is directed to a process for the production of denatured polyaddition products of biomasses and isocyanates, comprising reacting (A) from 5 to 98%, by weight, based on (A)+(B), of a biomass based on microorganisms or derivative and decomposition products thereof with (B) from 95 to 2%, by weight, based on (A)+(B), of a compound containing isocyanate groups, at temperatures of at least 50 DEG C. with complete denaturing of component (A).
