    Abstract: The present invention relates to a photoreactive polymer that comprises a multi-cyclic compound in a main chain, and a polymerization method thereof. Since the photoreactive polymer according to the present invention comprises a multi-cyclic compound having a high glass transition temperature as a main chain, the thermal stability is excellent, and since the mobility of the main chain is relatively high as compared to that of an additional polymer, a photoreactive group can be freely moved in the main chain of the polymer.

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.

  • Patent number: 8076434
    Abstract: The present invention has an object to provide an amphoteric polymer having high anti-soil redeposition ability and solubility with surfactants, and a process for producing the same. The amphoteric polymer includes: a structure unit (a) derived from a cationic group-containing monomer (A); and a structure unit (b) derived from a carboxyl group-containing monomer (B). The structure unit (a) is present at a level of 1 to 99% by mass based on 100% by mass of all structure units derived from all monomers in the amphoteric polymer, and the structure unit (b) is present at a level of 1 to 99% by mass based on 100% by mass of all the structure units derived from all the monomers in the amphoteric polymer.

  • Patent number: 8044156
    Abstract: Disclosed are multi-purpose polymers that are the polymerization product of a monomer mixture comprising at least one amino-substituted vinyl monomer; at least one nonionic vinyl monomer; at least one associative vinyl monomer; at least one semihydrophobic vinyl surfactant monomer; and, optionally, comprising one or more hydroxy-substituted nonionic vinyl monomer, crosslinking monomer, chain transfer agent or polymeric stabilizer. These vinyl addition polymers have a combination of substituents, including amino substituents that provide cationic properties at low pH, hydrophobic substituents, hydrophobically modified polyoxyalkylene substituents, and hydrophilic polyoxyalkylene substituents. The polymers provide surprisingly beneficial rheological properties in acidic aqueous compositions, and are compatible with cationic materials. The multi-purpose polymers are useful in a variety of products for personal care, health care, household care, institutional and industrial care, and industrial applications.

  • Patent number: RE45219
    Abstract: Provided are a photoreactive polymer that includes a multi-cyclicmulticyclic compound at as its main chain and a method of preparing the same. The photoreactive polymer exhibits excellent thermal stability since it includes a multi-cyclicmulticyclic compound having a high glass transition temperature at as its main chain. In addition, the photoreactive polymer has a relatively large vacancy so that a photoreactive group can move relatively freely in the main chain therein. As a result, a slow photoreaction rate, which is a disadvantage of a conventional polymer material used to form an alignment layer for a liquid crystal display device, can be overcome.
