Abstract
In accordance with the present invention, there are provided low viscosity acrylate monomers, and compositions based on same having low moisture resistance (and, hence are much less prone to give rise to “popcorning”), excellent handling properties (i.e., generally existing as a fluid material which does not require the addition of solvent to facilitate the use thereof), and excellent performance properties (e.g., good dielectric properties).

An acrylate derivative of optionally substituted bicycloheptenyl-containing optionally substituted polycyclic moieties.
A bifunctional acrylate monomer having one or more of the following structures:
- wherein:
- at least one of A and B, and/or one of C and D is a (meth)acrylate moiety,
- wherein any of A, B, C, and D that are not (meth)acrylate are H or a functional group,
- each R is independently a lower alkyl or a halogen,
- n is 1, 2 or 3,
- the sum of n′+n″ is 1, 2 or 3,
- n″′ is 1, 2, 3, 4, or 5,
- m is 1, 2, 3, 4, or 5,
- each x is independently 0, 1 or 2, and
- x′ is 0, 1, 2.
A bifunctional monomer according to the following structure:
- X—Y—Z
- wherein:
- Y is an optional bridging group,
- X is an acrylate derivative of an oligomer of optionally substituted cyclopentadiene, a radical having one of the following structures:
- wherein:
- A or B is a (meth)acrylate moiety, wherein the non-(meth)acrylate member of the A/B pair is H,
- each R is independently a lower alkyl or a halogen,
- n is 1, 2 or 3
- the sum of n′+n″ is 1, 2 or 3,
- n″′ is 1, 2, 3, 4, or 5,
- m is 1, 2, 3, 4, or 5,
- each x is independently 0, 1 or 2, and
- x′ is 0, 1, 2, and
- Z is a trimer, tetramer or pentamer of optionally substituted cyclopentadiene bearing at least one functional group, a radical having one of said structures (IX), (X), (XI), (XII), (XIII), (XIV) or (XV), an epoxy, or a cycloaliphatic moiety bearing at least one functional group.
