Abstract
Abstract Solutions in reactive diluents of a solid thermoplastic macromonomer of of the formula R(̵Z)̵ n X where R is a hydrocarbon containing up to about 20 carbon atoms, Z is a vinyl aromatic monomer, n is a positive integer such that the number average molecular weight of Z is about 2,000-50,000, and X is a polymerizable ethylenically unsaturated end group, are radiation curable to various low shrinkage products including heatsealable films, pressure sensitive adhesives, coatings, embedments, extrudates, moldings and composites such as laminates. The addition prior to curing of materials such as elastomers, tackifiers, flow control agents, oligomers or mixtures thereof further enhances the properties of the compositions.
