Title:
CYCLOOLEFIN-BASED POLYMER
Document Type and Number:
Japanese Patent JP2006274166
Kind Code:
A
Abstract:
To provide a cycloolefin-based polymer capable of being melt-kneaded at a low torque when melt-kneaded in an extruder, and having excellent moldability.
The cycloolefin-based polymer has ≥0.52 proportional constant A obtained by the relation [equation (1): log[η]=A×log[Mw]+B] between an intrinsic viscosity (η) and a weight average molecular weight (Mw) obtained by a GPC method, and is soluble in tetralin at 135°C.
