A process for co-production of an alkenyl aromatic compound such as, for example, styrene and t-butylstyrene, and an oxygenated sulfur-containing compound such as, for example, a sulfoxide or a sulfone is disclosed which comprises: (1) contacting, in the presence or absence of a catalyst, an .alpha.-methyl benzylic hydroperoxide with an organic sulfide compound to produce a mixture of an .alpha.-methyl benzylic hydroxide and an oxygenated sulfur-containing compound; (2) separating the .alpha.-methyl benzylic hydroxide from the sulfur-containing compound; (3) contacting the .alpha.-methyl benzylic hydroxide with a base to convert the .alpha.-methyl benzylic hydroxide to the alkenyl aromatic compound; and optionally, (4) recovering the alkenyl aromatic compound from the oxygenated sulfur-containing compound. The sulfoxide produced can be oxidized to a sulfone. The contacting of the .alpha.-methyl benzylic hydroxide with a base can also be carried out before the .alpha.-methyl benzylic hydroxide is separated from the oxygenated sulfur-containing compound followed by separation of the sulfur-containing compound.

Co-production of an alkenyl aromatic compound or precursor thereof and

A process is provided for producing a poly(arylene sulfide) polymer which employs at least one base as a reactant, wherein the base is contacted with the polymerization reaction mixture incrementally during the polymerization.

Process for preparing poly(arylene sulfide) polymers

A composition that, when present in a polymer matrix, reduces the deleterious effect of UV light absorption by the polymer is provided, which comprises a sulfur-containing derivative of hydroxyphenylbenzotriazole having the formula of: ##STR1## wherein each X is selected from the group consisting of hydrogen, halogens, cyano, alkyl, phenyl group, biphenyl group, arylthio, amine, ketone, aldehyde, alkoxy, hydroxy, carboxylic acid group, oligomer and combinations thereof and can have carbon atoms up to about 20; n is a whole number from 1 to 5; n' is a whole number from 0 to 4; n' is a whole number from 1 to 2 and each n' can be the same or different; q is an integer from 1 to 10; each Y is selected from the group consisting of --S(O)(O)--, --S(O)--, and --S--; each R can be selected from the group consisting of hydrogen, alkyl group, alkenyl group, aralkyl group, alkaryl group, and combinations thereof and can have 0 to about 10 carbon atoms; each OH group can be at either the 2'- or the 6'-position, or both.
