The ‘Baylis - Hillman Reaction’ mechanism and applications revisited
摘要:
It is shown that reaction of aryl, benzyl, alkyl and functionalised alkyl acrylic esters with benzaldehyde, in the presence of 1,4-diazabicyclo[2.2.2] octane, strongly depends upon the electronic and steric effects of the ester part. This influence is also observed in condensation of furfuraldehyde. Moreover, for the first time, it is shown that the overall condensation is equilibrated.

The present invention provides a powder coating comprising associated particles having an average particle diameter of 3-70 µm, said associated particles containing fine polymer particles having an average particle diameter of 0.01-2 µm.
The powder coating of the present invention comprises powder coating particles which have a relatively narrow particle size distribution, which have a relatively small average particle diameter, and which are controlled in shape. Moreover, the powder coating can be produced at a high yield, is greatly superior in fluidity and electrifiability as compared with conventional powder coatings; gives a coating film having excellent luster and sufficient smoothness; and can be applied in a thin film.

A production method of electrostatic latent image developing toner, comprising: a colored particle forming step of forming colored particles in water-based medium; a first separation step of separating the colored particles from the water-based medium; a dispersing step of dispersing the colored particles into a washing medium; a skimming step of skimming impurities other than the colored particles together with at least a part of the washing medium, the impurities drifting on the washing medium; and a drying step of dry the colored particle so as to make the water content of the colored particles being 3% or less.
A responsive microgel is provided which responds volumetrically and reversibly to a change in one or more aqueous conditions selected from the group consisting of (temperature, pH, and ionic conditions) comprised of an ionizable network of covalently cross-linked homopolymeric ionizable monomers wherein the ionizable network is covalently attached to an amphiphilic copolymer to form a plurality of ‘dangling chains’ and wherein the ‘dangling chains’ of amphiphilic copolymer form immobile micelle-like aggregates in aqueous solution. A responsive microgel is further provided that comprises at least one therapeutic entity and delivers a substantially linear and sustained release of the therapeutic entity under physiological conditions.
