摘要:
Provided is a thermoplastic resin having excellent thermal conductivity, in which thermoplastic resin a change in number average molecular mass caused by progress of polymerization occurring when the thermoplastic resin material is melted and a change in thermal conductivity caused by the change in number average molecular mass are low. The thermoplastic resin has (A) a specific structure and (B) ends of molecular chains sealed by a monofunctional low molecular weight compound. The resin itself has excellent thermal conductivity. The change in number average molecular mass becomes small during melting of the thermoplastic resin material, so that the change in thermal conductivity of the resin itself becomes small.

摘要:
The present invention provides a thermally-conductive organic additive which (i) is an organic polymer, unlike a thermally-conductive inorganic filler such as ceramic, metal and a carbon material, (ii) is capable of imparting thermal conductivity to plastic by being added thereto, (iii) can reduce the weight of a composition even when added to a resin in a large amount, without causing abrasion on molds and deteriorating an electrical insulation property of the composition, and (iv) provides the composition with excellent molding processability. The present thermally-conductive organic additive includes a liquid crystalline thermoplastic resin which has a mainly-chain structure, wherein a main chain of the liquid crystalline thermoplastic resin contains mainly a repeating unit represented by the general formula (1): -M-Sp- (1) wherein M represents a mesogenic group; and Sp represents a spacer, the liquid crystalline thermoplastic resin itself having thermal conductivity of not less than 0.45 W/(m·K).
