Abstract
Disclosed are a composition comprising polyether compounds, obtained by addition copolymerization of a mixture of 4-vinylcyclohexene-1-oxide and a compound having at least two epoxy groups with a compound having at least one active hydrogen atom, and a composition comprising epoxy compounds obtained by epoxidation of the composition of the polyether compounds. The invention also relates to processes for production thereof. The disclosed composition comprising epoxy compounds has a higher softening temperature compared that produced by polymerization of only 4-vinylcyclohexene-1-oxide with a compound having at least one active hydrogen atom.
