Title:

GRAFTING-MODIFIED CYCLIC POLYMER, PROCESS FOR PRODUCING THE SAME, AND CURABLE COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2001/083576

Kind Code:

A1

Abstract:

A grafting-modified cyclic polymer which is obtained by grafting an unsaturated organic compound having a polar group onto a polymer having a ring structure, has a grafting percentage of 10 to 150 mol% and a weight-average molecular weight of 1,000 to 1,000,000, and either has a gel content of 0.1 wt.% or lower or gives, through gel permeation chromatography, a differential elution curve in which the higher-molecular-weight side and the lower-molecular-weight side which are separated from each other with the perpendicular from the peak top to the base line have respective areas (Ha) and (La) and the (Ha)/(La) ratio is 1.6 or lower; and a curable composition comprising the grafting-modified cyclic polymer and a hardener.
