Title:
RESIN CONTAINING INDOLE SKELETON, EPOXY RESIN CONTAINING INDOLE SKELETON, EPOXY RESIN COMPOSITION AND CURED PRODUCT THEREFROM
Document Type and Number:
WIPO Patent Application WO/2006/043524
Kind Code:
A1
Abstract:
The present invention relates to an epoxy resin providing a cured product being excellent in high heat resistance, moisture resistance and flame resistance, and in the adhesion with a different type of material, and also to a resin containing an indole skeleton used as an intermediate for the epoxy resin. The above resin containing an indole skeleton is prepared by reacting 100 moles in total of an indole and a phenol with 10 to 90 moles of a crosslinking agent such as an aldehyde and a xylylene glycol. The above epoxy resin containing an indole skeleton is prepared by the epoxidation of the above resin containing an indole skeleton with epichlorohydrin. The resin containing an indole skeleton can be represented by the following general formula (1): H-L-(X-L)n-H (1) wherein L is a divalent group formed from an indole or a phenol, the presence ratio (mole ratio) of an indole-derived group and a phenol-derived group is in the range of 1:9 to 9:1, X is a divalent group formed from a crosslinking agent such as an aldehyde, a ketone, xylylene glycol or divinyl benzene, and n represents a number of 1 to 10.
