| abstract |
The present invention relates to a novel grafting method for (meth) acrylates in which the reaction is initiated by isocyanates and special imin-structured bases. With this new and specifically usable method, polymers, in particular polyolefins, which have double bonds, grafted or crosslinked in a suitable reaction. Furthermore, these unsaturated polymers can be used after a reaction with (poly) isocyanates for the preparation of graft or block copolymers or for the attachment of the modified unsaturated polyolefins to polyamides, polyesters, polycarbonates, polyimines or polyurethanes. |
