The laminate of claim 14 wherein the polymer having more than one perfluorocyclobutane group segregates from the material having a different composition such that it imparts thereto increased flame resistance, chemical resistance, hydrolytic stability, lubricity, environmental protection, scratch resistance, solvent resistance, surface passivation, water repellancy, lower surface refractive index, lower surface coefficient of friction, fluid barrier properties, oil repellancy, thermal stability, or reduced moisture pick-up over the same property the material would have in the absence of the polymer having more than one perfluorocyclobutane group.
