-carboxylic acids; (c) 0 to 30% by weight of vinyl acetate; and (d) 0 to 39% by weight of at least one additional free-radically copolymnerizable monomer; wherein the % by weight content of components (a), (b), (c) and (d) totals 100%, and with the proviso that the total amount of component (b) and component (c) combined is 1 to 40% by weight based on the copolymer, are described along with methods of using such copolymers to solubilize substances which are insoluble in water, substances which are only sparingly soluble in water, and combinations thereof.
This application relates to derivatives of hydrocarbon terpenes (e.g., myrcene or farnesene), to methods of making the derivatives, and to the use of the derivatives as surfactants.

A first object of the present invention is to provide a method for producing a carboxyl group-containing water-soluble polymer capable of giving neutralized viscous solutions excellent in thickening effect even when the aqueous solutions of the carboxyl group-containing water-soluble polymer have a low concentration. A second object of the invention is to provide a method for producing a carboxyl group-containing water-soluble polymer capable of giving neutralized viscous solutions excellent in thickening effect at low concentration levels and, at the same time, capable of being dispersed and dissolved in water at high concentrations with ease.
The prevent invention is a method for producing a carboxyl group-containing water-soluble polymer by reacting an α,β-unsaturated carboxylic acid and a compound having two or more ethylenically unsaturated groups in the presence of a radical polymerization initiator, which method is characterized in that the reaction is carried out in the presence of a (meth)acrylic acid derivative represented by the general formula (1):
(in the formula, R
1
and R
2
each independently represents a hydrogen atom or a methyl group and n represents 1 or 2).

A new class of molecules, C1-OH tributanoylated hexosamines, including, for example, Ga1NAc, G1cNAc and ManNAc, are demonstrated to increase cartilage-like tissue accumulation by IL- 1β-stimulated chondrocytes. Furthermore, all three molecules reduced NFKB1 and ΙκΒα driven gene expression, consistent with NFκB inhibitory properties of these analogs. Ga1NAc-a exposure produced the greatest ECM accumulation by IL-Ιβ- stimulated chondrocytes. However, Ga1NAc-a exposure produced an opposite effect on MSC exposure, where a decrease in ECM accumulation was observed. These findings are in support of the function of NFκB signaling during limb development and growth plate chondrogenesis. The present invention shows the capability of this new class of hexosamine analogs as disease-modifying agents for treating cartilage damage.
