Abstract

A macromolecular material with fibrous or flakey structure is produced in the form of a thin sheet. It is strong and has a good feel and flexibility. A soln./dispersion of a cpd. with >=2 reactive H atoms and di- or poly-isocyanate plus catalyst are reacted in a thin layer at a low temp. such that the solvent/dispersant crystallises.
