    摘要： The present invention relates to a polythiol composition that includes (a) a polythiol compound (A) having at least two thiol groups; and (b) a nitrogen-containing compound (B) represented by the following Formula (I), In Formula (I), —S—R is a residue of the polythiol compound (A). A peak area of the nitrogen-containing compound (B) is equal to or less than 3.0, with respect to a peak area of 100 of the polythiol compound (A). Each peak area for compounds (A) and (B) is determined by high performance liquid chromatography analysis. The present invention also relates to a polymerizable composition that includes the polythiol composition, and polymerizates thereof.

    摘要： Unsymmetrical organic disulfide sulfinate compounds, useful as an antiradiation agents, having the general formula: ##STR1## wherein A is one or of the following polar groups, OH, COOH, SO.sub.3 Na, --C(O)--, or derivatives such as esters and nonamino nitrogen derivatives such as amides or nitriles; k is an integer of one to eight; Y is a straight or substituted aliphatic chain haivng from two to eight carbon atoms which may have one or more S--S groups interposed therebetween; m signifies the number of carbon atoms in an aliphatic chain Y containing 2 to 8 carbon stoms which may have S--S interposed; aliphatic chain Y, substituted with one or more polar groups of the number k is attached to one of the two sulfur atoms shown. The second sulfur atom is attached through an aliphatic chain of 2 to 5 carbon atoms to the sulfinate function SO.sub.2 M wherein R.sup.1 and R.sup.2 may be hydrogen, aryl, cycloalkyl or various polar groups such as OH, COOH, SO.sub.3 Na, --C(O)--, or derivatives such as esters and nonamino derivatives such as amides or nitriles. The system ##STR2## also may comprise an aromatic ring; n may be the integers 2 through 6; M of the sulfinate function is hydrogen, a metallic element selected from group 1 A of the Periodic Table such as Li, Na, or K, or the equivalent R.sub.4 N+; or an organic group such as a straight or substituted aliphatic chain having up to 4 carbon atoms, designed to promote stability. The synthesis of the compounds occurs by subjecting 1,1-dioxides of cyclic disulfidesto the action of a thiolate ion, whereby cleavage is effected between the sulfur and sulfonyl units.
