ABSTRACT OF THE DISCLOSURE The present invention relates to copolymerizable macromolecular monomers comprised of linear polymers or copolymers having one terminal moiety which contains two functional groups of substantially equivalent reactivity in participating in a condensation copolymerization reaction with difunctional condensible comonomers or prepolymers wherein the macromolecular monomers have substantially the same molecular weight. The present invention also relates to chemically joined, phase separated graft copolymers of the copolymerizable macromolecular monomers with at least two different condensible difunctional comonomers capable of reacting with each other and at least one of which is capable of reacting with the terminal moiety on the macromolecular monomers. Alternatively, the copolymerizable macromolecular monomers may be copolymerized with preformed polymeric seg- ments which are the reaction products of at least two different condensible difunctional comonomers and which have a functional group on each end of the segments capable of reacting with the terminal moiety on the macromolecular monomers.
