Select the functional group needed to improve your polymer - C&EN

Select the functional group needed to improve your polymer . . . and choose the appropriate Rohm and Haas methacrylate monomer for copolymerization

Methacrylic Acid. Carboxyl groups in copolymers can impart: improved adhesion properties, better stability in polymer emulsions, reactive centers for crosslinking, solubility in alkalies. Dimethylaminoethyl Methacrylate. t-Butylaminoethyl

Methacrylate.

Amine groups can: promote adhesion to many substrates, provide anchoring sites for dyes and pigments, serve as reactive sites for crosslinking, permit preparation of acid-soluble polymers. Methacrylamide. Amide groups can: improve resistance to solvents, improve dyeing capacity, provide sites for crosslinking. Hydroxyethyl Methacrylate or Hydroxypropyl Methacrylate. Hydrox-

yl groups can: promote adhesion to selected substrates, offer sites for crosslinking.
