Complex formation poly acrylic acids with glycols

The problem of complex formation of the copolymers stabilized by hydrogen bonds has been studied very insufficiently. Until recently, there have been available various data both on the complex formation in the maleic acid/styrene-poly(ethylene glycol) system71 and the matrix polymerization of acrylic acid with acrylamide of styrene copolymers in the presence of N-vinylpyrrolidone641. 

Another special type of blend SMP is poly(acrylic acid-co-methyl methacrylate)/poly(ethylene glycol) (P(AA-co-MMA)/PEG) blends, whiA form hydrogen-bonded complexes [52]. It was found that both the concentration and molecular weight of PEG have a strong effect on the complexation with P(AA-co-MMA) gel. In such a system the minimum molecular weight of PEG required for the complex formation lowers to 1000.
