摘要：
The present invention is directed to a process for the production of a modified cellulosic product by: 1) coating or impregnating a composition of: a) a polymethylene poly(phenyl isocyanate), b) water, and c) an organic compound having an hydroxy functionality of from 2 to 8, and having a molecular weight of from about 60 to about 8000, and being selected from the group consisting of i) ester group-free polyhydric alcohols, ii) polyether polyols and iii) mixtures thereof, and 2) allowing the impregnated cellulosic material to cure at room temperature and without application of pressure.
