Disclosed herein is a frambinone methacrylate (FMA) or raspberry ketone methacrylate (RKMA) monomer having the following structure: and Also disclosed are homopolymers and co-polymers utilizing same monomer. Also disclosed is a class of methacrylate monomers comprising a bio-based moiety and a reactive ketone moiety. Also disclosed are paint compositions made with a copolymer including FMA and/or ZMA.

Bio-based monomers and polymers made therefrom

Disclosed herein is an aqueous latex composition comprising a substantially acrylic core-shell latex, wherein a water-retaining monomer is copolymerized to the shell. The Tg of the core ranges from about 0&#xb0; C. to about 12&#xb0; C., and the Tg of the shell ranges from about 13&#xb0; C. to about 40&#xb0; C. The mean volume average particle size of the latex ranges from about 125 nm to about 200 nm. The core-shell latex comprises at least one acrylic monomer having a solubility that ranges about 10 g/L to about 30 g/L at 30&#xb0; C., and this at least one acrylic monomer is present in the shell polymer in an amount greater than about 50 wt. % of all monomers in the shell. Preferably, the at least one acrylic monomer is methyl methacrylate.

Multi-stage latex particles with peg in outer stage

The present invention provides amic acids and imides derived from a polymer comprising: (a) maleic anhydride, (b) a first C-Calkyl vinyl ether monomer, and (c) a second C-Calkyl vinyl ether monomer, wherein the polymer contains an amic acid or an imide group. The polymers containing an amic acid or an imide group of the invention may be employed in a wide variety of compositions, particularly in oral care compositions. Non-limiting generic structures of the amidic polymers are set out below: (I) wherein R-R, M, a, b, c, d, e, and f are defined herein. 

Amic acids and imides derived from terpolymers

Branched polymers are prepared from at least (A) at least one monomer having an electron donor moiety, (B) at least one monomer having an electron acceptor moiety, and (C) at least one multifunctional branching agent comprising a urea moiety and at least two N-vinyl groups. The branched polymers are least 20% (by weight) soluble in a solvent for which the corresponding polymer of equal molecular weight made without said multifunctional branching agent is at least 20% (by weight) soluble. Due in part to the wide range of chemistries and solubility and rheological properties, the branched polymers find application in personal care, pharmaceutical/nutritional, and performance chemicals compositions.
