Title:
RESIN COMPOSITION, MOLDED BODY, AND OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/189303
Kind Code:
A1
Abstract:
Provided is a resin composition including an alicyclic structure-containing polymer, with which the problem of threading properties during injection molding is improved, and excellent strength is imparted to an injection-molded article. The present invention is a resin composition including an alicyclic structure-containing polymer, wherein the ratio of the area of the component of polymers having molecular weights of a hundred thousand or more in terms of polyisoprene to the whole area of a GPC chart obtained by GPC measurement using an RI detector is 0.5%-20%, and formula (1): Mz/Mw ≥ Mw/Mn is satisfied when the z-average molecular weigh, weight-average molecular weight, and number-average molecular weight in terms of polyisoprene in the GPC measurement are denoted as Mz, Mw, and Mn, respectively.
