Abstract

A polymerizable composition which comprises a cycloolefin monomer (A), a filler (B), a polymer (C) having a carboxyl group or a carboxylic acid anhydride group and having an acid value of 0.1 to 100 mgKOH/g, and a metathesis polymerization catalyst (D). The polymerizable composition comprises a cycloolefin monomer and a large amount of a filler, and has a low viscosity and is excellent in fluidity, and further can provide a molded product which is excellent in the lowness of dielectric constant, the lowness of dielectric loss tangent, the lowness of linear expansion coefficient, high heat resistance and adhesiveness, and further is free of bubble inclusion.

Claims (15)

1. A polymerizable composition comprising:

a cycloolefin monomer (A),

a filler (B),

a polymer (C) having a carboxyl group or a carboxylic anhydride group and having an acid value in the range of 0.1 to 100 mgKOH/g, and

a metathesis polymerization catalyst (D).

2. The polymerizable composition according to claim 1 , further comprising a chain transfer agent.

3. The polymerizable composition according to claim 1 , further comprising a crosslinking agent.

4. The polymerizable composition according to claim 1 , further comprising a chain transfer agent and a crosslinking agent.

5. A molded product obtained by bulk polymerization of the polymerizable composition as claimed in claim 1 .

6. The molded product according to claim 5 , obtained by coating the polymerizable composition on a supporting body, followed by bulk polymerization.

7. The molded product according to claim 5 , obtained by injecting the polymerizable composition into a cavity of a forming mold, followed by bulk polymerization.

8. The molded product according to claim 5 , obtained by impregnating a fiber reinforcement with the polymerization composition, followed by bulk polymerization.

9. A crosslinked resin molded product obtained by bulk polymerization of the polymerizable composition as claimed in claim 3 , followed by crosslinking of the bulk polymer.

10. A crosslinked resin molded product obtained by heating and melting a molded product obtained by bulk polymerization of the polymerizable composition as claimed in claim 4 so as to be crosslinked, at the temperature higher than the peak temperature during the bulk polymerization.

11. A crosslinked resin composite obtained by laminating a molded product obtained by bulk polymerization of the polymerizable composition as claimed in claim 4 on a base material, followed by heating and melting the laminate.
