  • Patent number: 4548761
    Abstract: Process for the preparation of 1-aminobenzene-2-sulphonic acids of the formula ##STR1## wherein R.dbd.H or a substituent andn=1-4,and their salts, in particular their alkali metal salts, by oxidation of compounds of the formula ##STR2## wherein R.sub.1 .dbd.H, a cation, in particular an alkali metal cation, or a radical of the formula ##STR3## characterized in that the oxidation is carried out in a weakly acidic to alkaline pH range. The process can also be carried out as a one-pot process, using the corresponding benzothiazoles as starting materials.

  • Patent number: 4438259
    Abstract: Di(vinylaryl)alkyl polysulfides and curable, low odor (vinylaryl)alkyl-terminated polysulfide copolymers having the general structure ##STR1## wherein n is an integer from about 2 to about 8, 1 and m are positive integers, each R is independently an organic polyradical with the radicals residing on carbon atoms, p is zero or a positive integer which is the difference between the number of radicals on R and 2, and each Z is independently chosen from the class consisting of (vinylaryl)alkyl and other noncrosslinking monoradicals, provided that a sufficient proportion of the Z groups are (vinylaryl)alkyl that the polymer, when cured, does not cold flow. Additionally, a method of preparing said polymers and useful adhesive, sealant and caulking compositions made therefrom are disclosed.
