Unsaturated compounds containing silane, electron donor and electron acceptor functionality
View Patent ↗This invention relates to curable compounds or resins containing electron donor or acceptor functionality, carbon to carbon unsaturation, and silane functionality, having the structure: in which E is an electron donor or electron acceptor functionality; Q is an oligomeric or polymeric group containing at least one carbon to carbon double bond, A is a hydrocarbyl group; and L is a linking group.
1. A curable compound having the structure
(i) Q is an oligomeric or polymeric group containing at least one carbon to carbon double bond;
(ii) R 1 is a methyl or ethyl group;
(iii) R 2 is a vinyl group, an aromatic group, or a linear or branched alkyl group of 1 to 4 carbon atoms;
(iv) A is a hydrocarbyl group;
(v) L is a linking group resulting from the reaction of a functional group on the precursor for the segment containing silane and a functional group on the precursor for the segment Q;
(vi) n is simultaneously for each position 0,1, or 2;
(vii) L′ is an organic moiety resulting from the reaction of a functional group on Q and a functional group on E′.
(viii) E′ is an organic moiety containing an electron donor functionality or an electron acceptor functionality or an epoxy functionality.
2. The curable compound according to claim 1 in which Q is derived from a poly(butadiene) precursor.
3. The curable compound of claim 1 in combination with a curing agent and optionally a filler.
4. The curable compound of claim 1 in combination with a curing agent and optionally a filler, in which the combination is disposed and cured between a silicon chip and a substrate.
