Five styrenic monomers, four with aminoalkyl residues typical of copper containing amine oxidase substrates and one with a 2,6-dialkoxybenzylamine residue which mimics previously prepared selective substrate-like benzylamine oxidase inhibitors, have been synthesized and transformed into radical homopolymers, copolymers with N,N-dimethylacrylamide (DMAA), and hydrophilic beaded resins, designed for enzyme interaction studies aimed in finding new materials for highly biospecific chromatographic separations. The five monomers have given beaded resins of 125-500 μm swellable in water with a volume increase of 1200-1500%. The four aminoalkyl monomers have given water soluble copolymers some of which are good substrates of benzylamine oxidase (BAO), diamine oxidase (DAO) and lysyl oxidase (LO), up to 9.7 times better than elastin for LO.

The anionic polymerization of a substituted styrene with α-methylstyryl moiety, 4-(4-(2-isopropenylphenoxy)butyl)styrene (1), was carried out in THF at -78 deg C with sec-BuLi as an initiator. In the anionic polymerization, only the styryl group of 1 can

Cross-linked polymer-bound lithium dialkylamides were employed in crossed aldol reaction of various carbonyl compounds with aldehydes to afford the corresponding β-hydroxycarbonyl compounds. The introduction of spacer chains to the polymer-bound lithium d

In a process for producing hydroxyalkyl (meth)acrylates by the reaction of (meth)acrylic acid with an alkylene oxide, a thermally and chemically stable anion exchange resin is used as a catalyst, which resin contains a repeating unit represented by the following formula (1) as a component: wherein A is a straight chain alkylene group having 3 to 8 carbon atoms, each of R1, R2, and R3is a hydrocarbon group or an alkanol group having 1 to 4 carbon atoms, which may be substituted with a hydroxyl group, X?is a counter ion coordinated with an ammonium group, where the substituent A with the ammonium group may be substituted at any position of a benzene ring, and the benzene ring may be substituted with an alkyl group or a halogen atom. The process can economically efficiently produce hydroxyalkyl (meth)acrylates without disadvantages such as deterioration in properties of a distillation residue.
