  • Mono(cyclobutarene)/polymaleimide copolymers
    Patent number: 5247037
    Abstract: Copolymers of a mono(cyclobutarene) comonomer and a polymaleimide comonomer are described. These copolymers have higher thermal stability and lower water absorption than polymaleimide homopolymers. They are useful in applications such as electronics, membranes, composities, coatings, and adhesives. Examples of such copolymers are those formed from the comonomers 1,1'-(methylenedi-4,1-phenylene)bismaleimide, and 3-(1-(4-methylphenyl)ethenyl)-bicyclo(4.2.0)octa-1,3,5-triene or 3-(2-(4-methylphenyl)ethenyl)-bicyclo(4.2.0)octa-1,3,5-triene.
