Abstract of the Disclosure COMPATIBILIZED POLYMERIC SYSTEMS Polymer blends which take advantage of the best properties of all of the polymers in the blend can sometimes be made. However, in many cases it is not possible to make such blends because the polymers are dissimilar and incompatible. For example, blends of nylon with nitrile rubber which exhibit the best properties of both the nylon and the nitrile rubber cannot normally be made because nitrile rubber and nylon are very incompatible. This inventions discloses a technique for compatibilizing two or more dissimilar polymers which contain nitrile groups, hydroxyl groups, carboxyl groups, amide groups, amine groups, or mercapto groups. The subject invention more specifically relates to a process for preparing a compatibilized blend of a first polymer which contains nitrile groups, hydroxyl groups, carboxyl groups, amide groups, amine groups or mercapto groups and a second dissimilar polymer which contains nitrile groups, hydroxyl groups, carboxyl groups, amide groups, amine groups or mercapto groups, which comprises reacting a polymer, such as rubber having pendant blocked isocyanate groups bound thereto with the first polymer and the second dissimilar polymer.
