Abstract
Aliphatic cyclobutene compositions according to the formula ##STR1## can be homopolymerized or copolymerized with a variety of comonomers, including bismaleimides, to produce tough, low dielectric constant resins.
Claims10
A composition of matter of the structural formula ##STR13## in which each R is selected independently from hydrogen, halide, C.sub.1-10 alkyl, aryl and C.sub.1-10 heteroatomic;
- X is a carbonyl linking group and X' is selected from hydrogen and carbonyl linking groups.
