IPN powder coatings were prepared which were composed of (A) a pendant double bond-containing ac rylic resin made by reacting m-isopropenyl-a-a-dimethylbenzyl isocyanate (TMI) and a hydroxyl-containing acrylic resin and (B) a bisphenol type epoxy resin of high molecular weight cured by means of a ca
A possible model for the formation of interpenetrating polymer networks is suggested. Phase separation is assumed to be faster than gelation. This implies that domains rich in either component grow first until late stages of spinodal decomposition. In these domains, short linear chains are crosslink
Interpenetrating polymer networks (IPNs) composed of polyurethanes and epoxies were prepared by the simultaneous technique. Modifications of the polymer structures resulted in a series of IPNs exhibiting semimiscible behavior, as evidenced by broad glass transitions in the dynamic mechanical spectra
