Abstract

A resin composition including a resin component and glass fibers, the resin component including 0 to 99 wt % of a hydrogenated crystalline cycloolefin ring-opening polymer that includes a repeating unit derived from a polycyclic norbornene-based monomer that includes 3 or more rings, and does not include a polar group, and 1 to 100 wt % of a hydrogenated modified crystalline cycloolefin ring-opening polymer that includes a repeating unit derived from a polycyclic norbornene-based monomer that includes 3 or more rings, and includes a polar group, the resin composition including the glass fibers in an amount of 5 to 150 parts by weight based on 100 parts by weight of the resin component; and a resin formed article obtained by forming the resin composition.

First claim

The invention claimed is:

1. A resin composition comprising a resin component and glass fibers, the resin component comprising 0 to 99 wt % of a hydrogenated crystalline cycloolefin ring-opening polymer that comprises a repeating unit derived from a polycyclic norbornene-based monomer that includes three or more rings, does not comprise a polar group, and has syndiotacticity, and 1 to 100 wt % of a hydrogenated modified crystalline cycloolefin ring-opening polymer that comprises a repeating unit derived from a polycyclic norbornene-based monomer that includes three or more rings, and comprises a polar group, the resin composition comprising the glass fibers in an amount of 5 to 150 parts by weight based on 100 parts by weight of the resin component.

2. The resin composition according to claim 1 , wherein the hydrogenated modified crystalline cycloolefin ring-opening polymer that comprises a repeating unit derived from a polycyclic norbornene-based monomer that includes three or more rings, and comprises a polar group, is a polymer produced by subjecting a hydrogenated crystalline cycloolefin ring-opening polymer that comprises a repeating unit derived from a polycyclic norbornene-based monomer that includes three or more rings, and does not comprise a polar group, to graft modification using an unsaturated carboxylic acid or a silicone derivative.

3. A resin formed article obtained by forming the resin composition according to claim 1 .

4. The resin formed article according to claim 3 , the resin formed article being an electronic part.

5. A resin formed article obtained by forming the resin composition according to claim 2 .

6. The resin formed article according to claim 5 , the resin formed article being an electronic part.

7. The resin composition according to claim 1 , wherein the resin component comprises 50 to 97 wt % of the hydrogenated crystalline cycloolefin ring-opening polymer and 3 to 50 wt % of the hydrogenated modified crystalline cycloolefin ring-opening polymer.

8. The resin composition according to claim 1 , comprising the glass fibers in an amount of 30 to 90 parts by weight based on 100 parts by weight of the resin component.

9. The resin composition according to claim 1 , which is a mixture of the resin component and the glass fibers.

10. The resin composition according to claim 1 , having a dielectric loss tangent at 1 GHz of 0.002 or less, and a bending strength of 170 MPa or higher.

11. The resin composition according to claim 1 , having a dielectric loss tangent at 1 GHz of 0.001 or less, and a bending strength of 180 MPa or higher.

12. The resin composition according to claim 1 , wherein the hydrogenated modified crystalline cycloolefin ring-opening polymer has syndiotacticity.

13. The resin composition according to claim 2 , wherein the graft modification is carried out using a silicone derivative.
