Reaction of Glycidyl Containing Polymer with Phenol Formaldehyde Resins

Acrylic resins containing pendant amine groups can be obtained by the use of acrylamide or methacrylamide. One method of producing pendant methylol groups on the polymer chain is by the reaction of an amide containing polymer with formaldehyde, to produce methylol groups. 

The methylol groups are normally stabilised by reaction with an alcohol (usually propanol or butanol) to form an alkoxy methylol group. 

Both the methylol and alkoxy methylol groups will readily react with xy, carboxy, hydroxy and amino groups. In addition the unstabilised meAylol groups readily undergo self condensation. 

The methylol groups will condense with alkoxy methylol groups 0 o 

The alkoxy methylol groups will also self condense under the appropriate conditions of heat and acid catdysis.
