A process for preparing a composition by free-radical polymerization of a monomer composition comprising: a) at least one ethylenically unsaturated carboxylic acid containing monomer or anhydride thereof; b) optionally at least one ethylenically unsaturated monomer different from a) but copolymerizable therewith; and c) at least one crosslinking monomer containing at least two ethylenically unsaturated groups. The monomer composition is polymerized in an organic medium having a solubilizing effect on one or more of the monomeric ingredients, but substantially none on the resulting polymer. The polymerization is conducted in the presence of a free radical forming catalyst and at least one steric stabilizing polymer polymerized from a vinyl lactam and a copolymerizable monomer selected from a short chain alkyl ester of (meth)acrylic acid, a long chain alkyl ester of (meth)acrylic acid, and combinations thereof.

The present invention novel methods of preparing biomimetic proteoglycans, such as bottle-brush, chondroitin sulfate-containing, biomimetic proteoglycans. In certain embodiments, the methods of the invention comprise contacting a core polymer comprising at least one acyl chloride group with a GAG comprising a terminal primary amine.

An itaconate molecule can have the formula: wherein R1 and R2 are each independently selected from H, Ag, or Cu; wherein the ratio of Ag and/or Cu to itaconate is at least about 1:1; and wherein n ranges from 1 to 14. The itaconates are useful, for example, as antimicrobial agents.
