Family of non-homopolymers synthesized from N-vinyl lactam, (meth)acrylic acid, hydrophobic (meth)acrylic ester of a straightchain or branched-chain alkyl alcohol and monomer selected from the group consisting of functionalized and unfunctionalized: dialkyl maleates, dialkyl fumarates, and combinations thereof. The non-homopolymers may exhibit solubility in one or more lower molecular weight alcohols and/or a glass transition temperature greater than 80&#xb0; C. 

Polymers polymerized from at least four monomers, and compositions and uses thereof

Described herein are multifunctional polymers comprising a first repeating unit having at least one pseudo-cationic moiety, a second repeating unit having at least a hydrophobic moiety, and a third repeating unit, where the weight-average molecular weight is less than about 10,000 Da. In one embodiment the polymers exhibit antimicrobial activity. Also provided are compositions formulated with the multifunctional polymers, and a method of providing antimicrobial activity.

Multifunctional polymers

Described herein is a class of non-homopolymers polymerized from at least: (A) 10-22 mole percent of at least one N-vinyl lactam, (B) 30-35 mole percent of at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, and combinations thereof, (C) 40-52 mole percent of at least one (meth)acrylate of a straight- or branched-chain alkyl alcohol, and (D) 5-20 mole percent of at least one (meth)acrylate of a saturated or unsaturated cyclic alcohol having 6 to 20 carbon atoms. In one embodiment, the non-homopolymers exhibit solubility in the lower molecular weight alcohols. The non-homopolymers may be used in personal care or performance chemicals compositions. In one embodiment, the polymers are used in various personal care formulations, such as used for skin, sun, hair, and preservatives.
