Paragraph 0045; 0046, (2014/09/03)
Disclosed herein are derivatives of phenolic and melamine compounds, methods of making these derivatives, and methods of using them. The compounds include phenolic and melamine compounds with multi-functional acrylate groups, polyethylene glycol and amino groups. The compounds may be cured to form resins that may be used in a variety of applications, such as paints, hydrogels, polyacrylate super absorbent polymers (SAPs), adhesives, composites, sealants, fillers, fire retardants, crosslinking agents, and the like.

A total of 13 of the 16 possible methylol derivatives of 2,4′- and 4,4′-dihydroxydiphenylmethane have been synthesized, isolated, and identified. These compounds are found as intermediates in the cure process of resol phenol-formaldehyde (PF) resins. Analysis of the 13C NMR spectra (in acetone-d6) of these compounds provided a way to evaluate the seven methylolphenol ring types (methylol derivatives of 2-hydroxyphenyl and 4-hydroxyphenyl rings) found in typical resol PF resins using the ipso carbon region from 150 to 160 ppm. A simple diagnostic test was developed using the chemical shift values of the methylol methylene carbon atoms to identify the presence of intermediates containing either a 2-hydroxyphenyl or a 4-hydroxyphenyl ring. Using these data it is now possible to analyze the major components in extracted prepreg PF resins. Copyright
