Block copolymer containing segments of poly( dimethylsiloxane) (PDMS) and ketonic resins were synthesized. Dihydroxy-terminated PDMS were reacted with the isophorone diisocyanate (IPDI) to obtain the diisocyanate-terminated PDMSs (urethane). These urethanes were reacted with reactive hydroxyl groups in the cyclohexanone-formaldehyde, acetophenone-formaldehyde, and in situ melamine-modified cyclohexanone-formaldehyde resins.
