Abstract
To provide a resin material having high heat resistance and adhesiveness while having low relative permittivity and dielectric tangent. A polyfunctional vinyl resin represented by the following general formula (1), wherein each R1 represents a hydrocarbon group having 1 to 8 carbon atoms, each R2 represents a hydrogen atom or a group represented by formula (2) or formula (3); and each X represents a hydrogen atom or a vinyl group-containing aromatic group represented by formula (1a)
Claims12
A polyfunctional vinyl resin represented by the following general formula (1):
- wherein each R1 independently represents a hydrocarbon group having 1 to 8 carbon atoms, each R2 independently represents a hydrogen atom, a group represented by formula (2), or a group represented by formula (3), and at least one R2 is represented by formula (2) or formula (3);
- each R3 independently represents a hydrogen atom or a hydrocarbon group having 1 to 8 carbon atoms, and each R4 independently represents a hydrogen atom or a group represented by formula (2);
- A represents a residue obtained by removing two R2 from the formula (1) and each R2 in the residue independently represents a hydrogen atom or a group represented by formula (2);
- Me represents a methyl group;
- each X independently represents a hydrogen atom or a vinyl group-containing aromatic group represented by the formula (1a), at least one is a vinyl group-containing aromatic group, and Ar represents an aromatic ring;
- i is an integer of 0 to 2;
- and each of n and p 1 represents the number of repetitions and an average value thereof is a number of 0 to 5.
