  • Coextrusion binder composition and coextruded multilayer composite in which the said composition is employed as adhesive layer
    Patent number: 6657006
    Abstract: This composition includes: at least one out of (A1) the graft polymers resulting from the grafting of at least one grafting monomer such as maleic anhydride onto (a) impact or crystal styrene homopolymers and copolymers and/or (b) optionally hydrogenated styrene-diene elastomer block polymers, (b) not being the only polymer in the mixture of (A) and (B); (A2) at least one copolymer (b) mixed with at least one polymer (B1); (A3) graft polymers resulting from the cografting of at least one grafting monomer onto a mixture of at least one polymer (a) and of at least one of (c) ethylene-vinyl acetate copolymers, ethylene-alkyl (meth)acrylate copolymers, ethylene homopolymers, and ethylene-&agr;-olefin copolymers; (A4) graft polymers resulting from the cografting of at least one grafting monomer onto at least one polymer (a) to which at least one tackifying resin (d) has been added, these graft polymers being mixed with at least one polymer (B1); and optionally at least one out of (B1) graft polymers resulti

  • Diurethane latex and processes
    Patent number: 4892620
    Abstract: A sizing agent for paper consisting essentially of a latex consisting essentially of at least one diurethane dispersed in an aqueous medium, said diurethane being of the formula: ##STR1## in which: (a) R.sub.1, R.sub.2, R.sub.5 and R.sub.6 are each alkyl radicals and at least one of them possesses a minimum of 7 carbon atoms;(b) R.sub.7 and x represent, respectively, the cationic and anionic portions of the quaternizing agent R.sub.7 x;(c) R.sub.3 and R.sub.4 are selected from C.sub.2 -C.sub.4 alkylene radicals or polyalkoxylated radicals of a degree of polycondensation of between 1 and 4; and(d) Y is ##STR2## The process of making the sizing agent and using it to size paper are also disclosed.
