  • Patent number: 4409363
    Abstract: The invention relates to a process for the manufacture of a mixture of a polycarbonate and a styrene-containing polymer whereby the polycarbonate present in solution is initially brought into contact with a precipitating agent. The solvent and the precipitating agent are subsequently separated from the precipitated solid material to prepare a polycarbonate having residual moisture of more than 1 and less than 50 percent by weight relative to the polycarbonate, and where the resultant product with a residual moisture is mixed with the styrene-containing polymer at temperatures above the softening range of the components removing volatile components. The claimed mixtures are suitable for the manufacture of molded parts for cars, bottles and appliances.

  • Patent number: 4408084
    Abstract: Acetal-coupled non-ionic surfactants are easily degraded into relatively environmentally inoccuous fragments having little or no surface activity. The fragments are sufficiently low in molecular weight to be oxidized when exposed to water and atmospheric oxygen. The surface activity can also be destroyed by lowering the alkalinity of the medium in which the non-ionic surfactant is utilized to below pH 7. The non-ionic surfactants of the invention unexpectedly have very low viscosities as compared to surfactants containing a comparable molecular weight and oxyalkylene residue content.
