    摘要： Organoclay compositions which comprise the reaction product of a smectite-type clay having an ion exchange capacity of at least 50 meq. wt. per 100 g. clay (active basis), and mixture of a quaternary ammonium compound and a chain transfer agent which is a thiol, .alpha.-methylketone, .alpha.-methylalcohol or a halogen compound are useful agents for use in the processes for the preparation of thermoplastic materials.

    摘要： Increased ion exchange capacity per unit weight of substrate is achieved upon using as the substrate regenerated cellulose sponge instead of cotton fabric. A water soluble crosslinkable polymeric material having ion ion exchange sites, such as polyvinyl phosphate or polyethylenimine, and a suitable crosslinking agent are dissolved in water. The sponge is wetted with the solution and dried and cured at about 100 degrees to 145 degrees C. to crosslink the polymer to the substrate. The so-prepared ion exchange composition is immersed in a flowing stream of dilute aqueous solution of heavy metal ions or otherwise contacted with such solution to effect separation and concentration of such cations.

    摘要： A thermoplastic laminate structure consisting of a plurality of layers wherein at least one of the layers is the adhesive polymeric blend. The adhesive polymeric blend comprises a dispersed phase of poly-2-oxazoline and a glycol and a continuous phase of grafted polypropylene. The preferred poly-2-oxazoline is poly-2-ethyl-2-oxazoline and the preferred glycols are polyalkylene glycols. The grafted polypropylene comprises from about 50 to 80 percent by weight of the total polymeric blend. The grafted polypropylene contains from about 0.1 to about 5 percent by weight total polymer of a graft portion derived from an .alpha.,.beta.-ethylenically unsaturated carboxylic acid or an unsaturated cyclic anhydride wherein said glycol is in slight excess to the graft, i.e., molar ratio of glycol to graft is 1.1 to about 1.5:1.
