Abstract
An improved process for preparing a one component self-crosslinking resin is provided. The process for making the self-crosslinking resin is carried out by copolymerizing an oxime-blocked m-isopropenyl-alpha, alpha-dimethylbenzyl isocyanate (m-TMI), hydroxyethyl acrylate, and another unsaturated monomer at 75.degree. C. to 85.degree. C. in a polar organic solvent having a dipole moment of at least 3, such as acetonitrile. The polar solvent retards the thermal deblocking of the blocked TMI, thereby preventing the premature self-crosslinking and gelation of the copolymerization product prior to its use as a self-crosslinking resin.
