  • Patent number: 8242205
    Abstract: A novel method of preparing an aqueous dispersion of non-uniform polyurethane particles which comprises (a) preparing at least two isocyanate-terminated polyurethane prepolymers having different hydrophilicities; (b) preparing a uniform mixture of said prepolymers, and (c) dispersing the mixed prepolymers in an aqueous medium. The resulting dispersion of the prepolymers may optionally be chain extended. This method enables the preparation of core-shell particles as well as particles of other morphologies, including “raspberry”, interpenetrating network, “salt-and-pepper”, “ice-cream cone” and particles of gradient composition. Similarly, an aqueous dispersion of two different polyurethane polymers may be obtained by first preparing at least two different isocyanate-terminated polyurethane prepolymers, preparing a uniform mixture of such prepolymers and thereafter dispersing the mixture in an aqueous medium.

  • Patent number: 7455909
    Abstract: A polymeric dispersion in aqueous phase for use as a polymeric binder for paper and other nonwoven articles is described utilizing a polyisocyanate in combination with said polymeric binder to increase the ratio wet tensile/dry tensile strength. The polyisocyanate seems to be functioning by increasing the fiber to binder interaction rather than by simply increasing the strength/crosslink density of the binder. The polyisocyanate can be blocked isocyanate(s) or water dispersible isocyanate(s). The binder may or may not have isocyanate reactive species along the backbone.

  • Patent number: 6316107
    Abstract: An emulsion or suspension polymer comprising a vinyl chloride polymeric core and an acrylic ester-acrylonitrile polymeric shell is disclosed. The emulsion polymer is preferably prepared using a two-stage process. In the first stage, a vinyl chloride monomer is polymerized or copolymerized to form a first phase of a polymeric hard core having a relatively high chlorine content. In a second stage, the soft acrylic ester—acrylonitrile copolymer is made in situ in a reaction mixture comprising the first phase. The product provides both flame retardancy and low MFFT, and is useful in a variety of coating and binding applications.

  • Patent number: 6020438
    Abstract: An emulsion polymer comprising as one of its components a graft copolymer of a residual aromatic monomer-free support resin polymer and a vinyl chloride (co)polymer is disclosed. The emulsion polymer is prepared using a two-stage process. In the first stage, a chasing monomer is reacted in the presence of a support resin polymer having at least one aromatic monomer to form an polymer which is free of residual monomer and has monomeric units derived from the aromatic monomer(s). In a second stage, the vinyl chloride emulsion (co)polymer is made in situ in a reaction mixture comprising the polymer which is free of residual monomer. An extensive grafting at the second stage yields a novel water dispersible graft copolymer containing both styrene and vinyl chloride.

The latex can only be formed in an aqueous medium by an emulsion polymerization process in which at least one-half of the IA is initially charged into a reactor, and the remaining ingredients of the receipe then added gradually. This unique order of addition produces a highly stable latex of polymer particles having a glass transition temperature (T.sub.g) in the range from about -20.degree. C. to about -60.degree. C.
