Copolymers glycol methyl ether acrylate

Recent attempts to prepare 26 by RAFT, however, failed [153]. Double hydrophilic block copolymers of NIPAM and 23e [154], as well as of N,N-diethylacrylamide and 23b [155], were prepared with the CTA benzyl dithiobenzoate, and exhibit LCST and UCST behavior in water. The new polymer 51 is also part of amphiphiUc di- and triblock copolymers [152]. Diblock copolymers with poly(ethylene glycol) methyl ether acrylate, dimethylacry-lamide, or 4-vinylstyrene sulfonate are macrosurfactants with a switch-able hydrophobic block. Triblock copolymers containing additionally 4-vinylbenzoic acid differ in the nature of the hydrophilic part [152]. Near-monodisperse block copolymers of N,N-dimethacrylamide and 49a were synthesized in different ways via macro-CTAs of both monomers as the first step. Such sulfobetaine block polymers form aggregates in pure water but are molecularly dissolved after addition of salt [152,156,157].

Solvents influence the rate of free-radical homopolymerization of acrylic acid and its copolymerization with other monomers. Hydrogen-bonding solvents slow down the reaction rates. Due to the electron-withdrawing nature of the ester groups, acrylic and methacrylic ester polymerize by anionic but not by cationic mechanisms. Lithium alkyls are very effective initiators of a-methyl methacrylate polymerization yielding stereospecific polymers.Isotactic poly(methyl methacrylate) forms in hydrocarbon solvents. Block copolymers of isotactic and syndiotactic poly(methyl methacrylate) form in solvents of medium polarity. Syndiotactic polymers form in polar solvents, like ethylene glycol dimethyl ether, or pyridine. This solvent influence is related to Lewis basicity in the following order ... 

The resin is highly compatible with a glycol ether dialkyl ether. Thus, a mixed solution composed of the acrylic resin and the glycol ether can easily be prepared. The acrylic resin is produced from alkyl methacrylates, aralkyl methacrylates, alkoxyalkyl methacrylates, hydroxyalkyl methacrylates, methacrylic acid, or dialkyl-aminoalkyl methacrylates. A particularly preferred copolymer is a copolymer of methyl methacrylate and methacrylic acid. 

In acrylic latices, the hard monomer is methyl methacrylate and the plasticizing monomer an acrylate, such as butyl acrylate or one of the acrylate comonomers mentioned above. Acrylic latices usually contain copolymers of acrylic or methacrylic acid as colloids and thickeners, these being solubilized by neutralization with base. Whatever the type of latex, coalescing solvents are also normally added to improve film formation. These may or may not be water miscible and include alcohols, glycols, ether-alcohols, ether-alcohol esters and even hydrocarbons, all of high boiled point. 

DPC has in recent years been applied to studies on a range of photopolymers including DF 2000 photopolymer [5], cinnamoylphenyl methacrylate-glycidyl methacrylate copolymer [6], multiethylene glycol dimethacrylate [7], Ebecryl 270 (aliphatic urethane diacrylate) 1,6-hexanediol diacrylate (Darocur 1173 2-hydroxy-2-methyl-phenylpropan-l-one) [8], epoxy acrylates [9], epoxy vinyl ether formulations [10], polyacrylates, maleimides, and vinyl ethers [11], hydroxylated poly(imides) [12], and polystyrene-poly(n-butylacrylate) copolymers [13].
