ABSTRACT:
Cyclic acetal derivative of a resole includes the reaction product of an ortho resole compound with a carbonyl compound or a carbonyl compound derivative. The cyclic acetal derivatives of phenolic resole compounds exhibit enhanced storage stability and can be readily activated at elevated temperatures to prepare phenolic based adhesives and coatings.
