Appeal No. 93-4332
Application 07/707,717
in which each R is selected independently from the group
consisting of hydrogen and C alkyl, R’ is a divalent linking
1-3
group, and the double bond separated from the conjugated pair
adjoins at least one hydrogen-bearing carbon atom.
3. The process of claim 2 in which R’ is C alkylene.
2-12
4. The process of claim 3 in which each R is selected from the
group consisting of hydrogen and methyl.
5. The process of claim 2 in which R’ is -O-R”-O-, in which R”
is selected from the group consisting of C alkylene and
2-12
phenylene.
6. The process of claim 1 in which the triene is myrcene.
7. The process of claim 1 in which the molar ratio of the
triene to the bisimide is within the range of about 0.2-1.0:1.
8. The process of claim 7 in which the triene is myrcene.
9. The process of claim 8 in which the bisimide comprises N, N-
4,4'-diphenylmethane bismalemide.
10. The process of claim 1 which further comprises from about
0.0002 to about 0.2 moles, per mole of the bisimide, of a free
radical polymerization inhibitor.
11. The process of claim 10 in which the free radical
polymerization inhibitor is phenothiazine.
12. The process of claim 9 in which the molar ratio of the
myrcene to the bisimide is within the range of about 0.4-0.8:1.
13. The process of claim 1 in which the elevated temperature of
step (b) is within the range of about 130 to about 200 C.0
14. The process of claim 9 in which step (b) is carried out for
a time sufficient to produce a thermosettable, partially-cured
mixture having a viscosity within the range of about 0.5 to about
10 Pa s..
