Abstract
Cellulose fibers are treated with vinyl chloride polymer, a plasticizer and an isocyanate bonding agent. Composites are made from cellulose fibers dispersed in a matrix of plasticized vinyl chloride polymer, and bonded thereto with an isocyanate bonding agent. The composites can be molded or extruded to produce useful articles.
