Abstract
Relatively low molecular weight Olefin/CO copolymers are graft copolymerized with vinyl monomers by the exposure of a mixture of a dispersion of the two to high energy radiation such as .gamma. ray radiation. Styrene is an example of a monomer useful in forming the graft copolymer. The graft copolymers are useful as waterborne glues particularly in the preparation of wood composites.
