    摘要： Compounds of the structure R(SCH.sub.2 CHOHCH.sub.2 X).sub.n when n=1 to 4 and R is a hydrocarbon, ether, ester, acetal, hydroxy aliphatic, hydroxy aromatic, imide or amide group or halogenated derivatives thereof are prepared by reacting 1-halo-3-mercapto-2-propanol with an aliphatically unsaturated compound using free radical initiators as catalysts. The compounds in which R is an unsaturated or polyunsaturated aliphatic hydrocarbon group of 2 to 24 carbon atoms, or an unsaturated or polyunsaturated cycloaliphatic group, and those in which the aliphatic or cycloaliphatic group is connected through two or more of the polyunsaturated to two or more --S--CH.sub.2 CHOHCHCl groups, and compounds where R is an alkylene or polyalkylene substituted aromatic group and the hydroxy, thioalkyl, alkoxy, aryloxy, ester, carbamidoalkyl and sulfamidoalkyl, halogenated derivatives of said groups are new compounds. The thioether halohydrins can be converted to epoxides. The process utilizing a radioactive energy source as a catalyst is new.

    摘要： An improved resinous structure is disclosed. The structure has a transparent resinous matrix having a light absorbance (optical density) at 640 millimicrons wavelength which is not greater than 0.07 when the structure has a thickness of 10 mils. The continuous matrix polymer is a polymer of about 65 to 95 parts by weight of styrene and 5 to 35 parts by weight of methylmethacrylate. The structure contains a discontinuous phase of a diene rubber in a proportion of about 4 to 12 parts by weight. The rubber is present in the form of particles having an average diameter not exceeding 2 microns, the particles are of a cellular nature and principally of a closed-cell configuration. The cell walls of the particles are not greater than about 0.15 microns in thickness. The rubber particles contain, occluded therein, polymer of a composition generally identical to the matrix polymer. Such resinous bodies are transparent, impact resistant and suitable for many packaging applications.

    摘要： Acrylonitrile-butadiene-styrene (ABS) resins are prepared by the mass or mass-suspension process employing a tertiary-butyl peroxy initiator having a 10-hour half-life between about 50.degree. and 95.degree.

From about 5 to 10 percent conversion to about 40 percent conversion is polymerized with agitation. The remaining polymerization is done with or without agitation. Improved impact resistance is obtained.
