摘要：
The present invention provides (1) curable bispropargyl-containing monomers represented by the formula: B.sup.1 --A.sup.1.sub.m --R--A.sup.2.sub.n --B.sup.2 wherein R is a radical selected from the group consisting of 1,4-phenylene, 4,4'-biphenyl, 2,6-naphthalene, --C.sub.6 H.sub.4 --CR.sup.2 .dbd.CR.sup.2 --C.sub.6 H.sub.4 -- wherein R.sup.2 is H or CH.sub.3, and the same where said groups contain one or more substituents selected from the group consisting of halo, nitro, lower alkyl, lower alkoxy, fluoroalkyl or fluoroalkoxy, A.sup.1 and A.sup.2 are selected from the group consisting of --C.sub.6 H.sub.4 --C(O)--O-- and --C.sub.6 H.sub.4 --O--C(O)--, m and n are 0 or 1, m+n is 0, 1 or 2, and B.sup.1 and B.sup.2 are --OCH.sub.2 --C.tbd.C--H, (2) thermoset compositions comprised of cured segments derived from monomers represented by the formula: B.sup.1 --A.sup.1.sub.m --R--A.sup.2.sub.n --B.sup.2 as described above, and (3) curable blends of at least two of the monomers.
