  • Publication number: 20150148475
    Abstract: The present invention provides telomeric copolymers of acrylic and methacrylic acid which further comprise an olefin polymerization residue and have one or more phosphorus acid groups wherein the phosphorus acid group comprises one or more phosphorus atom in the +1 oxidation state or in the +3 oxidation state, or both. In addition the present invention provides methods of making the telomeric copolymers comprising aqueous solution copolymerizing a monomer mixture comprising acrylic acid and methacrylic acid in the presence of a phosphorus acid group containing reactant having a phosphorus atom in the +1 oxidation state, and thermally treating the resulting telomeric copolymer at 175° C. or higher for a sufficient time to decarboxylate the copolymer.

  • Patent number: 8883886
    Abstract: The present invention provides thermosetting aqueous binder compositions of (i) one or more diprimary diamine, e.g. lysine, or poly(primary amine), e.g. polyethylenimine and tris(2-aminoethyl)amine, and (ii) one or more 5-carbon reducing sugar, such as xylose. The binders are at least substantially formaldehyde free and cure rapidly at temperatures sufficiently low and with sufficiently little swelling to enable one to provide wood or woody material containing articles, such as particle board, oriented strand board and bamboo boards or articles.

  • Publication number: 20140323743
    Abstract: The present invention provides hypophosphite (co)telomers of methacrylic anhydride having a weight average molecular weight of from 1,000 to 20,000, and having, on average, at least one phosphorus atom bound to two carbon atoms, and at least one carboxylic acid or salt group.

  • Patent number: 8859686
    Abstract: The present invention provides compositions of phosphorus acid group and methacrylic anhydride group containing telomeric copolymers of methacrylic acid having an as yet never achieved amount of more than 70 wt. %, or, preferably, 72 wt. % or more, and up to 99 wt. %, of methacrylic anhydride groups based on the total weight of polymerized methacrylic acid and/or salt units. The compositions enjoy higher thermal stability than was previously achieved and enable easer processing that does not require the removal of liquids or solvents.

  • Publication number: 20130323493
    Abstract: The invention provides aqueous thermosetting binder compositions exhibiting both of improved flame retardation and wet tensile strength comprising a reducing sugar, a diprimary diamine or a polyprimary diamine, a phosphorus acid salt and from 3 to 20 wt. %, based on total solids, of an aqueous polymeric polyacid solution polymer containing phosphorus or its salt, wherein the aqueous thermosetting binder composition comprises from 0.7% P (s/s) to 5% P (s/s).

  • Publication number: 20130323492
    Abstract: The present invention provides thermosetting aqueous binder compositions comprising one or more reducing sugar, one or more diprimary diamine or poly(primary amine), and from 7 to 45 wt. %, based on total solids, of one or more polysaccharide having a dextrose equivalent (DE) value of from 5 to 30. The compositions provide treated articles, such as fiberglass mat. The binders provide articles having a dramatically reduced binder weight loss upon cure and a reduction in cure energy needed to achieve early dry strength.

  • Publication number: 20110306726
    Abstract: The present invention provides thermosetting aqueous binder compositions of one or more cyclic enamine, including bis-enamines and di- or higher functional enamines, optionally containing a water soluble or dispersible or dispersible primary amine compound. The binders are at least substantially formaldehyde free, need no polycarboxylic or polycarboxylate component, and yet provide excellent hot wet tensile strength when cured for as little time as a minute or less in use.

  • Publication number: 20110262648
    Abstract: The present invention provides thermosetting aqueous binder compositions of one or more diprimary diamine, e.g. lysine, or poly(primary amine), e.g. polyethylenimine, and one or more reducing sugar in which the number of equivalents of primary amine relative to the number of equivalents of carbonyl groups in the reducing sugar ranges from 0.4:1 to 2:1, the binders being suitable for use on fiber, nonwoven, woven web and finely divided substrates. The binders are at least substantially formaldehyde free, need no polycarboxylic or polycarboxylate component, and yet provide excellent hot wet tensile strength when cured for as little time as a minute or less in use.
