N-hydroxysuccinimide-blocked isopropenyl-alpha, alpha-dimethylbenzyl isocyanate and self-cross linking copolymers thereof

摘要

A novel, one component self-crosslinking resin and a process for its preparation are provided. The resin is the copolymer of: (I) N-hydroxysuccinimide-blocked meta-isopropenylalpha, alpha-dimethylbenzyl isocyanate; (II) a hydroxy group-containing ethylenically unsaturated monomer such as hydroxyethyl acrylate; and (III) optionally, an ethylenically unsaturated monomer free of hydroxy groups such as methylmethacrylate or butyl acrylate. The copolymers are useful as thermally stable fast curing one component resins for paint, and produce, upon heat curing, films and objects with good hardness and solvent resistance.
