Abstract: The title compds.(II; R = C1-12 alkyl, C3-12 cycloalkyl,C7-11 aralkyl), useful as photostabilizers,polyolefin reformers and lubricating oil additives, were prepd. by the reaction of I and S2CI2 at -10-40≦̸C in-the presince of Lewis acid catalyst. Thus, 43.2 g p-cresol was treated with 22.6 g S2CI2 at 0-10≦̸C for 2 hr in the presence of 0.5 g ZncI,and the reaction products were stirred for 2 hr to give 42.8g 2,2'-bis(4-methylphenol)sulfides(m.p. 112-114≦̸C).

Abstract: The title compd.(I)' useful as photostabilizers and ployolefin reformers, Lubricating oil additives, Was prepd. by the reaction of 4-(1,1,3,3-tetramethylbutyl)phenol and S2CI2 at-10-40≦̸C in the presence of sulfating agent. Thus, 41.2 g 4-(1,1,3,3-tetramethylbutyl) phenol in 150 ml n-hexane was treated with 11.3 g S2CI2 at 0-10≦̸C for l hr, and the reaction products were stirred for l hr to give 40.4 g I(m.p. 135-136≦̸C).

Abstract: Blue-colored bioabsorbable surgical fibers are obtained by adding and dispersing a bioabsorbable polymer, which is selected from polyglycolic acid, poly(ℓ-lactic acid) and glycolic acid-ℓ-lactic acid copolymers all of which are useful as surgical fibers, and indigo in a non-aqueous organic solvent having low solubility for the polymer and indigo, heating the resultant dispersion at a temperature below l20°C to distill off the solvent, thereby to obtain a master batch with the indigo incorporated therein at a high concentration, mixing and kneading the master batch with a fresh supply of the polymer, and then spinning the resultant polymer mixture.

Abstract: Disclosed is a process for the preparation of 2,2'-bis(4-substituted phenol)sulfides which comprises reacting a 4-substituted phenol with sulfur dichloride in a hydrocarbon solvent at a temperature of from -10 DEG to 40 DEG C. in the presence of a Lewis acid catalyst. For example, 2,2'-bis(4-cumylphenol)-sulfide, i.e. 2,2'-bis(4- alpha , alpha -dimethyl benzyl-phenol)monosulfide, which is a novel compound can be prepared by reacting 4-cumylphenol with sulfur dichloride in benzene at a temperature of from 0 DEG to 10 DEG C. in the presence of zinc chloride.

Abstract: Disclosed is a color-developing composition for pressure-sensitive recording sheet material of the self-contained type comprising (A) 100 parts by weight of a copolymer obtained by reacting a p-alkylphenol having an alkyl moiety of from 1 to 12 carbon atoms and phenol with formaldehyde and (B) from 1 to 20 parts by weight of a hindered phenolic compound selected from phenols having an alkyl, alkylene or hydroxyl substituent radical in at least the 2- or 6-position, or both, of the benzene ring and derivatives thereof, the copolymer and the hindered phenolic compound being homogeneously dissolved in mutual solution. The hindered phenolic compound is either added to the starting materials for the preparation of the copolymer or, at the end of the copolymerization reaction, added to the resulting copolymer and dissolved homogeneously in mutual solution.
