CATIONIC COPOLYMERIZATION INVOLVING NCO-BEARING MONOMERS AND REACTIONOF THE ENSUING MATERIALS WITH THE SUPERFICIAL HYDROXY-GROUPS OF CELLULOSIC FIBERS

This paper describes the cationic polymerization of 3-isopropenyl-alph a,alpha'-dimethylbenzyl isocyanate (TMI) and its copolymerization with isopropenylbenzene (IPB) in order to synthesize materials with varyin g amounts of NCO side groups. These polymers were characterized by FTI R, H-1-NMR, elemental analysis and DSC. Their structure showed an esse ntially random incorporation of TMI. Preliminary reactions of the copo lymers with cellulosic fibers are also reported.
