Abstract
Abstract Object of the present invention is a glass fiber-reinforced norbornene polymer comprising a long glass fiber surface-treated with an amino group-containing silane coupling agent and a polymer obtained by ring-opening bulk polymerization of a norbornene monomer having a tricyclic or higher cyclic structure and a process for the production thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
37 words
A glass fiber-reinforced norbornene polymer comprising a long glass fiber surface-treated with an amino group-containing silane coupling agent and a polymer obtained by ring-opening bulk polymerization of a norbornene monomer having a tricyclic or higher cyclic structure.
Claim 2
Dependent Claim
37 words
A glass fiber-reinforced norbornene polymer comprising a long glass fiber surface-treated with an amino group-containing silane coupling agent and a polymer obtained by ring-opening bulk polymerization of a norbornene monomer having a tricyclic or higher cyclic structure.
Claim 3
Dependent Claim
23 words
A glass fiber-reinforced norbornene polymer as set forth in claim 1, wherein the amino group-containing silane coupling agent has an ethylenic double bond.
Claim 4
Dependent Claim
48 words
A process for the production of glass fiber-reinforced norbornene polymer, which comprises subjecting a norbornene monomer having a tricyclic or higher cyclic structure to ring-opening bulk polymerization by using a methathesis catalyst in the presence of a long glass fiber surface-treated with an amino group-containing silane coupling agent.
Claim 5
Dependent Claim
48 words
A process for the production of glass fiber-reinforced norbornene polymer, which comprises subjecting a norbornene monomer having a tricyclic or higher cyclic structure to ring-opening bulk polymerization by using a methathesis catalyst in the presence of a long glass fiber surface-treated with an amino group-containing silane coupling agent.
