Interaction Studies on Polymers

The formation of the polymer complexes between polyMAEA and polyMAEU was studied under similar conditions as for polymethacrylate derivatives47. PolyMAEA and polyMAEU form a stable 1 1 polymer complex in DMSO-EG. Hypochromitity of the polymer system increased slowly, and equilibrium was attained after 7 days (hypochromidty 66%). Formation of the complex depends on temperature and type of solvent used, as in the case of poly methacrylate38.  

Polymethacryloylamino type derivatives have a similar structure as polymethacry-loyloxy type ones, with a minor difference in side chain structure. However, the ability for forming polymer complexes is substantially higher for polymethacryloylamino derivatives than for polymethacryloyloxy type ones. PolyMAEA and polyMAEU can produce complexes even with monomers, that is, MAEU and MAEA, respectively, while the complex formation between polymers and monomers has never been observed in the case of methacryloyloxy type ones (Tables 15 and 16).
