Polymers polymerized from at least four monomers, and compositions and uses thereof
View Patent ↗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.
1. 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.
2. A formulation comprising a non-homopolymer is-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, t-butylaminoethyl (meth)acrylate, trifluoroethyl (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: a 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.
