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.
Claims2
A non-homopolymer polymer synthesized from monomers consisting of:
- (A) 24-26 mole percent of at least one monomer selected from the group consisting of:
- N-vinyl-2-pyrrolidone, N-vinyl-2-caprolactam, and combinations thereof,
- (B) 24-26 mole percent of a (meth)acrylic acid, and combinations thereof,
- (C) 35-38 mole percent of at least one monomer selected from the group consisting of:
- methyl (meth)acrylate, iso-butyl (meth)acrylate, trifluoroethyl (meth)acrylate, t-butylaminoethyl (meth)acrylate, and combinations thereof,
- (D) 12-13 mole percent di-iso-butyl fumarate, and
- (E) up to 5 mole percent of a monomer selected from the group consisting of:
- PEG/PPG (meth)acrylate, and combinations thereof,
- wherein:
- the total monomer content adds to 100 mole percent,
- the non homopolymer has a glass transition temperature of at least 80° C., and
- the non-homopolymer is soluble up to 50% (w/w) in a lower molecular weight alcohol.
