Polyacrylate-22 is a complex polymer that is prepared by first reacting isophorone diisocyanate (IPDI with a copolymer made from Adipic Acid and Neopentyl Glycol.
Definition
Polyacrylate-22 is a complex polymer that is prepared by first reacting isophorone diisocyanate (IPDI with a copolymer made from Adipic Acid and Neopentyl Glycol. The isocyanate groups on the resulting polymer are then reacted with hydroxyethyl methacrylate followed by quenching with ethanol to eliminate residual urethane groups. Finally, the polymer above is copolymerized with acrylic acid, methacrylic acid, and methyl methacrylate, then partially neutralized with aminomethyl propanol (AMP)
