Ketone resin solution compatibility

To achieve good compatibility with functionalized acrylic and epoxy resins a bis cyclic urea with n=3> and R=-(CH2)7-(see Scheme I) was synthesized. Acrylic- and epoxypolymer solutions were prepared using 15% by weight of the bis cyclic urea (based on the dry polymer) and methyl ethyl ketone as solvent. Films cast from these solutions on steel sheets were clear, and had a thickness of 0.4 mil.
