Abstract
Butadiene-polyether prepolymers which can be used in photopolymer resins are prepared by reacting butadiene homopolymer with a stoichiometric excess of isocyanate and then reacting the product with polyether diol. Thereafter the composition is reacted with hydroxyalkyl(meth)acrylate and alkyldialkanolamine. Flexographic printing plates may be prepared using photopolymer resin comprising butadiene-polyether prepolymers.
