    Abstract: Statistic comb polymers obtainable by the radical copolymerization of a vinylic poly(alkylenoxide) compound (A) with an ethylenically unsaturated monomer compound (B) according to the catalytic chain transfer method (CCT). The comb polymers are extremely suitable for hydraulic binder suspensions based on cement, lime, gypsum and anhydrite as they have, for the same dosage, an improved water reducing power over conventional flow agents. The corresponding building material mixtures are characterized by a substantially reduced stickiness and plastic viscosity once said comb polymers are added, which dramatically improves the plasticity of very cement-rich building material mixtures, such as concretes. The building material mixtures using the inventive flow agents have a considerably increased slump flow and an increased shear-thinning behavior as compared to conventional concretes without the tendency to segregate.

  • Publication number: 20120115963
    Abstract: A process for the preparation of a polymer nanoparticle by a photoinduced emulsion polymerization includes preparing an emulsion comprising at least one surfactant, a dispersed phase and a continuous phase. The dispersed phase comprises at least one polymerizable monomer and the continuous phase comprises water and at least one photoinitiator. The at least one polymerizable monomer is polymerized by exposing the emulsion to an electromagnetic radiation having a wavelength so as to induce a generation of radicals from the at least one photoinitiator.

  • Patent number: 8173751
    Abstract: The invention provides novel defoamers which are useful as defoamers for top coat paints for motor vehicles. When the defoamers are incorporated with paints which do not use melamine resins as the curing agent, they can impart defoaming property to the paints without inviting turbidity in the painted films caused by infiltration of water. Hence the defoamers are particularly useful when used for baking finish type clear top coat paints for motor vehicles. The defoamer is characterized by comprising a copolymer of 2-50% by weight of (A) a polymerizable monomer capable of forming a copolymer having isocyanate groups which can react with a binder resin in thermosetting type paint or (b) a polymerizable monomer capable of forming a copolymer having the groups which produce isocyanate groups reactable with a binder resin in thermosetting type paint during the baking step of the same paint, and 98-50% by weight of (C) a monomer or polymer conventionally used for defoamers.
