  • Patent number: 9487662
    Abstract: A radiation-curable composition comprising (meth)acrylic monomers and/or oligomers, photoinitiators, and a nonreactive composite additive, wherein the nonreactive composite additive comprises a) a biobased hydroxyurethane additive of formula (1): R1[—NH—COO—CR2H—CR3H(OH)]2??(1) wherein R1 is a residue of the biobased primary diamine, and R2 and R3 are the same or different and are selected from the group consisting of H, alkyl, and hydroxyalkyl; and b) a silane-based hydroxyurethane additive of formula (2): (R6)3-n(OR5)nSi—R4—NH—COO—CR2H—CR3H(OH)??(2) wherein R2 and R3 are the same as stated above, R4 is generally an aliphatic group having from 1 to 6 carbon atoms, R5 and R6, independently, are hydrocarbon radicals containing from 1 to 20 carbon atoms and selected from the group consisting of aliphatic, cycloaliphatic, and aromatic groups or combinations thereof, and n is equal to 1, 2, or 3.

  • Patent number: 9102829
    Abstract: A method of obtaining hybrid polyhydroxyurethane compositions cross-linked at ambient temperatures. The method comprises: (a) reacting epoxidized unsaturated fatty acid triglycerides with carbon dioxide in the presence of a catalyst to obtain carbonated-epoxidized unsaturated fatty acid triglycerides, wherein conversion of oxyrane groups to 2-oxo-1,3-dioxolane groups (cyclic carbonate groups) for said carbonated-epoxidized unsaturated fatty acid triglycerides ranges from 35% to 85%; (b) mixing and reacting the carbonated-epoxidized unsaturated fatty acid triglycerides with a compound having amine functionality comprising at least one primary amine group realized at stoichiometric or within nearly balanced stoichiometry; (c) mixing and reacting the product of step (b) with a compound having amine functionality comprising at least two primary amine groups realized at excess of an amine-functional compound; (d) subsequently mixing the product of step (c) with a compound having amino-reactive groups.

  • Patent number: 9051447
    Abstract: A polymer concrete composition, preferably for decorative and shock resistant building structures and goods includes a binder based of polyfunctional unsaturated compounds, namely acrylated/methacrylated vegetable oil, preferably acrylated/methacrylated soybean oil in an amount of not less than 60 part by weight and at least one acrylatedmethacrylated monomer and/or oligomer in an amount of not more than 40 part by weight, and an aggregate blend. The polymer concrete composition based on acrylated/methacrylated vegetable oil has high wear and shock resistance with low shrinkage and can be used for prefabricated building decorative structures and particularly in civil engineering.
