Process for the production of polyisocyanate lignin-cellulose plastics

摘要

This invention relates to a process for preparing polyisocyanate lignin-cellulose plastics by reaction of a lignin-cellulose polymer with a compound having at least two isocyanate groups to produce a lignin-cellulose polyisocyanate prepolymer. The prepolymer is then reacted with an organic compound to produce a polyisocyanate cellulose plastic.
