LCST-ポリマー
Document Type and Number:
Japanese Patent JP2006507399
Kind Code:
A
Abstract:
Lower critical solution temperature polymers obtained by co- or ter-polymerisation of (A) (macro)monomers based on N,N-dialkylacrylamide, N-vinylcaprolactam, methyl vinyl ether and/or N-vinyl-alkylamide with (B) maleic, fumaric or (meth)acrylic acid (or their derivatives), hydroxyalkyl (meth)acrylates, vinyl acetate and/or butadiene. LCST (lower critical solution temperature) polymers (I) obtained by radical co- or ter-polymerisation in aqueous or alcoholic solution of (A) 45.0-99.9 mol% monomer(s) or macromonomer(s) with structural units of (a) N,N-dialkylacrylamide; (b) N-vinyl-caprolactam ;(c) methyl vinyl ether and/or (d) N-vinyl-alkylamide: n, o, p, q = 1-10000; R1 = H or 1-5C alkyl; R2 = 1-5C (iso)alkyl and (B) 0.1-55.0 mol% of a comonomer selected from (a) maleic acid, maleic anhydride or 1-5C alkyl maleate, (b) fumaric acid or 1-5C alkyl fumarate, (c) (meth)acrylic acid or 1-5C alkyl (meth)acrylate, (d) 1-5C hydroxyalkyl (meth)acrylate, (e) vinyl acetate and/or (f) butadiene, optionally followed by derivatization (depending on the nature of B). Independent claims are also included for (1) a method as described above for the production of (I) (2) particles or non-particulate substrate surfaces coated with polymerized (I).
