Copolymers based on one or more ethylenically unsaturated monomers and at least one mono, bis or tris methynol phenyl-allyl ether, and process for their preparation

摘要

Copolymers produced from 0.5-20% by weight mono-, bis- or trismethylolphenyl allyl ether (I) of formula: IMAGE n being from 1 to 3, and from 80-99.5% by weight ethylenic monomers, at least one being a (meth)acrylic monomer are useful in the preparation of coatings, particularly in the field of paints, varnishes, inks and adhesives. Radical polymerization is employed with different stages of polymerization.
