Advanced epoxy resins containing in situ prepared addition polymers, process for preparation thereof and cured compositions containing same.

摘要

The present invention concerns the preparation of advanced epoxy resins containing in situ prepared addition polymers wherein said addition polymers are prepared in a relatively low equivalent weight epoxy resin and in the presence of a free radical initiator prior to advancing to a higher equivalent weight epoxy resin with a polyhydric phenolic compound or wherein as said addition polymers are prepared in the presence of an advanced epoxy resin in the presence of a free radical initiator.
