    Abstract: Liquid bromine-terminated polymers are directly prepared as by polymerizing one or more acrylates, acrylates in combination with isoprene, or butadiene with acrylonitrile using a combination of ultra-violet light and a dibromo-dichloro alkane containing at least two carbon atoms only as the polymerization initiator. These polymers are vulcanized with polyfunctional amines as curing agents to form solid elastomers, and are useful as base polymers for caulks, sealants, potting compounds, and like formulations.

    Abstract: A process for producing normal paraffin oximes and, in particular, normal paraffin oximes having from 14 to 50 carbon atoms wherein a C14 to C50 normal paraffin is photochemically reacted in the presence of a halogenated organic solvent with a nitrosating agent under the influence of light in the wavelength of 200 to 760 millimicrons and contacting the reaction product with a polybasic acid such as sulphuric or phosphoric acid. The oximes are subsequently recovered by neutralizing the acid treated product and separating the oxime.
