Method for preparing aceto acetoxy ethyl methacrylate

The invention discloses a method for preparing aceto acetoxy ethyl methacrylate. The method comprises the following steps of mixing hydroxyethyl methylacrylate with ethyl acetoacetate; then adding a supported inorganic solid base serving as a catalyst and methylhydroquinone serving as a polymerization inhibitor, and enabling a mixture to fully react at the temperature of 118-125DEG C; in the reaction process, distilling out ethanol serving as a reaction side product by adopting a mode of reacting while distilling; after the reaction is ended, separating the catalyst, thus obtaining a liquid product, namely the aceto acetoxy ethyl methacrylate. The method has the advantages of high reaction speed, few side reaction products and high yield.

POLYMER PARTICLES

The present invention relates to a method of forming polymer on the surface of polymer particles, the method comprising: (i) providing a dispersion comprising a continuous aqueous phase, a dispersed organic phase comprising one or more ethylenically unsaturated monomers, and a RAFT agent as a stabiliser for said organic phase; (ii) polymerising the one or more ethylenically unsaturated monomers under the control of the RAFT agent to form an aqueous dispersion of seed polymer particles; (iii) crosslinking the seed polymer particles; (iv) swelling the crosslinked seed particles with one or more ethylenically unsaturated monomers to form an aqueous dispersion of monomer swollen crosslinked seed polymer particles; (v) increasing the temperature of the monomer swollen crosslinked seed polymer particles to expel at least some of the monomer therein onto the surface of the particles; and polymerising at least the expelled monomer to form polymer on the surface of the particles.

Liquid oligomers containing acrylate unsaturation

The liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate functional donor compounds with multifunctional acrylate receptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from >/=1:1 to >/=13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate. Unuseable gelled or solid oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.
