The composition consists of an organic chemical/smectite clay intercalate that has been ion-exchanged and reacted and intercalated with one or more quarternary ammonium compounds and an anionic material and further blended into a polymer resin to make a nanocomposite composition. This material can be blended into a wide variety of polymers. This kind of system gives improved dispersion over conventional organoclays, intercalates or hybrid clays described in the literature, especially in non-polar resins. The defined organoclay has been found to be highly dispersible in a variety of polymers, whether polar or non-polar.

  • Patent number: 4695402
    Abstract: Improved organophilic clay gellants can be prepared by a process wherein the smectite-type clay is subjected to shearing in order to break apart the agglomerates and/or the smectite-type clay can be reacted with organic cation and, possibly organic anion, under dilute reaction conditions. The reaction product is recovered using gentle drying conditions. Depending in large part on its composition, the organophilic clay gellant may be used to thicken a variety of organic compositions. In a preferred aspect, the organophilic clay gellant can be directly added to polyester compositions in order to efficiently and effectively increase the viscosity thereof or can be first formed into a pregel under low shear conditions to yield even higher efficiencies.

  • Patent number: 4601839
    Abstract: Novel .alpha.-aminoacetamides are powerful stabilizers for organic materials subject to oxygen and heat degradation, and particularly for synthetic natural rubber, synthetic ester lubricants and synthetic resinous materials. A wide range of substituents on the amine and amide N atoms, at least one of which substituents is an alkylene imine (cyclic), and an even wider range of substituents on the saturated carbon atom, yields an array of stabilizers having a wide range of compatibility in compositions comprising various synthetic resinous compounds to be stabilized.Novel syntheses are provided utilizing at least one amine nucleophilic agent, a trichloromethide ion generating agent, and an alkoxide ion generating agent, which together in the presence of aqueous alkali and an onium salt, yield novel .alpha.-aminoacetamides in which a wide choice of substituents may be introduced. The nucleophilic agent may be a primary or secondary amine, or one of each. The trichloromethide ion generating agent is a haloform.

  • Patent number: 4555534
    Abstract: There is disclosed thickened, low shrinkage polyester molding compositions having improved pigmentation. The improved pigmentation in thickenable polyester molding compositions containing a carboxylated vinyl ester polymer low profile additive is achieved either by incorporating a surfactant in the composition, by using as the low profile additive a vinyl acetate/maleic acid copolymer, or by a combination of the two methods.
