A composition useful for molding into articles such as food containers, soft drink bottles, cured structural plastics and the like, comprising molding grade linear or unsaturated polyester or polycarbonate having reacted or copolymerized therein the residue of one or a mixture of styrylbenzazole reactants of the formula: ##STR1## wherein A is the residue of a benzene ring of a benzoxazole, benzothiazole or benzionidazole radical; X is --O--, --S-- or --N(R.sup.2)--; Ph is a phenylene radical; and R.sup.1 is halogen or --Y--R.sup.2 in which Y is --O-- or --N(R.sup.2)-- and each R.sup.2 is hydrogen, alkenyl or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical.

This invention relates to a process involving the reaction of a quinone with a carbonyl compound in the presence of a basic catalyst to produce 2,3-dihydro-2,5-benzofurandiols. These compounds are useful intermediates in the synthesis of herbicides and plant growth regulants.

2,3-Dihydro-3,3-dimethyl-2,5-benzofurandiol from isobutyraldehyde and

Dyestuffs of the anthraquinone series having a single anthraquinone nucleus substituted in one or two alpha positions of the nucleus with a --NHCH.sub.2 CH.sub.2 SO.sub.2 F radical.
