    摘要： Vinyl chloride is removed from aqueous slurries prepared by the suspension polymerization of a monomer component that comprises vinyl chloride by heating the slurries at a temperature between 70.degree. C. and the boiling point of water at a pressure in the range of 30 mm Hg absolute to 3 atmospheres and removing the evolved vinyl chloride until the aqueous slurry contains less than 50 ppm and preferably less than 0.1 ppm of vinyl chloride, based on the weight of polymer in the slurry. The polymers that are recovered from the purified aqueous slurries contain less than 10 ppm, and in most cases less than 0.1 ppm of vinyl chloride.

    摘要： The polymerization of a monomer component that comprises vinyl chloride in an aqueous medium in the presence of a free radical generating polymerization initiator is terminated by introducing into the polymerization reaction mixture when from 70% to 95% of the monomer component has been polymerized from 0.01% to 0.10% by weight, based on the weight of the monomer component, of a chain-terminating agent that is a dialkylhydroxyphenylalkanoic acid ester of a neopentyl polyhydric alcohol, such as pentaerythritol tetrakis-[3-(3,5-di-tert.butyl-4-hydroxyphenyl)propionate].

    摘要： An electrostatographic imaging member having a charge-retentive surface and a substrate, an imaging layer to receive an electrostatic latent image thereon, wherein the imaging layer is positioned on one side of the substrate, and an anti-curl backing layer positioned on the substrate on a side opposite to that of the imaging layer, wherein the anti-curl backing layer has a polymer binder and lignin sulfonic acid doped polyaniline, and an image forming apparatus having the above imaging member or photoreceptor to receive an electrostatic latent image on a charge-retentive surface of the photoreceptor or imaging member; a development component to apply toner to the charge-retentive surface to develop the electrostatic latent image to form a developed image on the charge-retentive surface; a transfer member to transfer the developed image from the charge-retentive surface to a copy substrate; and a fixing component to fuse the developed image to the copy substrate.
