Patent ID: 8637630

Claim:
A thermoplastic resin wherein: a main chain mainly has a repeating unit represented by a general formula (1); 60 mol % or more ends of molecular chains are sealed with a monofunctional low molecular weight compound; and thermal conductivity of the thermoplastic resin itself is not less than 0.45 W/(m·K), the general formula (1) being as follows: -A 1 - x -A 2 - y -R- z - (1) where: each of A 1 and A 2 independently represents a substituent group selected from the group consisting of an aromatic group, a fused aromatic group, an alicyclic group, and an alicyclic heterocyclic group; each of x, y, and z independently represents a direct bond or a bivalent substituent group selected from the group consisting of —CH 2 —, —C(CH 3 ) 2 —, —O—, —S—, —CH 2 —CH 2 —, —CH═CH—, —C≡C—, —CO—, —CO—O—, —CO—NH—, —CH═N—, —CH═N—N═CH—, —N═N—, and —N(O)═N—; and R represents a bivalent substituent group which has a main chain length of 2 to 20 atoms and may be branched.
