Allyl Cellulose (AC) was synthesized using allyl bromide in sodium hydroxide (NaOH)/urea aqueous solution. By employing a molar ratio of 6:1 of allyl bromide/cellulose, low-degree of substitution (DS) water-soluble AC (AC) was obtained (DS = 0.67).

These terpolymers, have been synthesized by radical copolymerization of methyl methacrylate, methacrylic acid, and sodium styrene sulfonate by varying the ratio R = [COO(-)]/[COO(-) + SO(3)(-)] from 0 to 1 and keeping ionic monomer content between 7 and 18%. Adsorption of fibronectin onto poly(methyl methacrylate) was shown to dramatically promote bacterial adherence, whereas a strong inhibition of bacteria adherence was observed onto functionalized terpolymers containing both carboxylate and sulfonate groups.
