Abstract
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° C.
Claims18
A non-homopolymer synthesized from at least the following monomers:
- (A) 9-32 mole percent of at least one N-vinyl lactam,
- (B) 24-30 mole percent of a (meth)acrylic acid, and combinations thereof,
- (C) 32-55 mole percent of at least one hydrophobic (meth)acrylic ester of a straight-chain or branched-chain alkyl alcohol, and combinations thereof,
- (D) 4-13 mole percent of a monomer selected from the group consisting of functionalized and unfunctionalized:
- dialkyl maleates, dialkyl fumarates, and combinations thereof,
- and optionally (E) up to 5 mole percent of one or more other monomers,
- wherein the total monomer content adds to 100 mole percent.
A formulation comprising at least one non-homopolymer synthesized from at least the following monomers:
