  • Publication number: 20080051497
    Abstract: The compositions of the present invention comprise silicone copolymers, terpolymers and higher order polymers that comprise 1) polyether substituted structural units and 2) epoxy or oxirane structural units that are reacted with acrylate species to produce cross linked silicones comprising polyether substituted structural units and acrylate cross links. The cross linked polymers of the present invention are self-emulsifying and may be either water swellable or oil swellable.

  • Publication number: 20060280716
    Abstract: The present invention discloses a method for making cationic, aminofunctional silicone emulsions particularly cationic emulsions having a low volatile cyclic siloxane content. The method of the present invention comprises an acid catalyzed emulsion condensation reaction of a mixture comprising hydroxy terminated polydimethylsiloxane and an aminosilane under conditions that do not allow for the generation of equilibrium cyclic oligomers followed by conversion to a cationic emulsion.

  • Patent number: 6207782
    Abstract: Emulsions and dispersions of polymers formed from acrylated hydrophilic polysiloxanes and their copolymers with acrylate/methacrylate comonomers are taught herein wherein the polymer is formed in a solvent via radically catalyzed polymerization. Such a polymer has utility in personal care applications, as well as textile finishes and coating formulations.

  • Patent number: 5981681
    Abstract: The present invention discloses non-hydrolyzable, block, (AB).sub.n A type, copolymers comprising alternating units of polysiloxane and amino-polyalkyleneoxide and provides a method for the preparation of these copolymers. Also provided is the use of these copolymers as softeners, in particular durable, hydrophilic textile softeners, which improve tactile properties of the textiles substrates treated with the commercial soil release finishes, without substantially detracting from their properties. The copolymers of the present invention have alternating units of polysiloxane [X(C.sub.a H.sub.2a O).sub.b R.sup.2 [(SiO(R.sup.1).sub.2 ].sub.c Si(R.sup.1).sub.2 R.sup.2 (C.sub.a H.sub.2a O).sub.b X] and polyalkyleneoxides [YO(C.sub.a H.sub.2a O).sub.d Y] wherein R.sup.1 is a C.sub.1 to C.sub.4 alkyl, preferably methyl, R.sup.

  • Patent number: 5939574
    Abstract: Aminosiloxanes bearing 4-amino-3,3-dialkylbutyl substituents are prepared by a multistep process including addition of 2,2-dialkylacetonitrile to vinylic siloxanes, hydrogenation of the nitrile adducts so formed to yield 4-amino-3,3-dialkylbutyl siloxanes, and optional equilibration of the latter with other siloxane sources, to form aminosiloxanes, which are useful for the treatment of textiles and fabrics and for the preparation of siloxane-containing block copolymers.
