    摘要: The present invention relates to an energy curable aqueous composition (X) comprising (a) Water; (b) At least a water-insoluble ethylenically unsaturated compound (A); (c) At least one (meth)acrylic polymer (B1) containing ionic functional groups that are at least partly neutralized by a neutralizing agent (C) and/or at least one (meth)acrylic hybrid (B2) containing ionic functional groups that are at least partly neutralized by a neutralizing agent (C); and (d) At least one nonionic emulsifier (D) comprising alternating polyalkylene oxide segments, said nonionic emulsifier (D) having an HLB value of at least 4.5. Materials of the invention are suitable for the preparation of inks, overprint varnishes or coating compositions.

    摘要: A continuous process for making a comb-branched copolymer of an acrylic monomer and a polyether macromonomer is disclosed. The process is performed by continuously feeding a reaction zone with a monomer stream that contains an acrylic acid and a polyether macromonomer, and an initiator stream. The comb-branched copolymer made thereby performs better as water reducing agent in cement compared to that made by a batch process.
