The present invention relates more particularly to reactive resins comprising high-boiling, reactive (meth)acrylic monomers from the group of the polar, cyclically substituted esters of (meth)acrylic acid, more particularly glycerol acetal, ketal or carbonate methacrylates. These new components are used as substitutes for MMA, which represents the major part of the odour nuisance in the existing, prior-art reactive resin systems. Using these new components it is possible to obtain resin formulations which have glass transition temperatures similar to, and properties comparable with, MMA-based resins. The innovative reactive resins are able in addition to exhibit more rapid curing than prior-art MMA-based systems. Reactive resins for the purposes of the invention are reactive monomer mixtures or mixtures of monomers and polymers that when used as a 2-component system can be readily cured.

  • Publication number: 20140024765
    Abstract: An application to a resin material and a polymerization method of a polymerization agent having a polymerizable surface structure and a mechanism of supplying the polymerization agent, the polymerization agent exhibiting a polymerizing function in contact with the surface of the resin material. The resin material is obtained by living radical polymerization of a radical polymerization initiator exhibiting living property and an unsaturated monomer capable of radical polymerization with the polymerization initiator. The polymerization agent is brought into in contact with the surface of the resin material to induce radical re-polymerization of the polymerization agent. As a result, a damaged portion of the resin material can be repaired or the resin materials can be bonded to each other by way of the polymerization agent, which can suppress formation of the hetero-interface or improve the service life of the resin material.

  • Publication number: 20130277599
    Abstract: The present invention concerns polymers obtained by anionic initiation and bearing functions that can be activated by cationic initiations that are not reactive in the presence of anionic polymerization initiators. The presence of such cationic initiation functions allow an efficient cross-linking of the polymer after moulding, particularly in the form of a thin film. It is thus possible to obtain polymers with well-defined properties in terms of molecular weight and cross-linking density. The polymers of the present invention are capable of dissolving ionic compounds inducing a conductivity for the preparation of solid electrolytes.

    Abstract: A target variable analysis unit (11) calculates the triad fractions of monomer units in the composition of a known polymer sample from the copolymerization reactivity ratios of the monomer units to obtain a target variable. A waveform processing unit (12) processes NMR measurements, signals, etc. An explanatory variable analysis unit (13) obtains explanatory variables from the amount of chemical shift and signal strength in the NMR measurements of the known sample. A model generation unit (14) determines the regression equation of the regression model of the target variable and the explanatory variables by partial least squares regression, and obtains regression model coefficients. A sample analysis unit (15) uses the regression model to calculate the triad fractions for an unknown copolymer sample from the amount of chemical shift and signal strength in the NMR measurements of the unknown copolymer sample.
