International Classification:

C07C15702
C07C15705
C07C16100

US Classification:

560147

Abstract:

Novel isothiouronium salts are herein described which correspond to the formula ##STR1## wherein R and R' are each independently hydrocarbyl or inertly-substituted hydrocarbyl of at least 4 carbon atoms; R. sub. 1 -R. sub. 4 are each independently alkyl or hydroxyalkyl of 1 to 4 carbon atoms, or R. sub. 1 and R. sub. 3 are joined to form a 5- or 6-membered heterocyclic ring; n is 0 or 1; and A. sup. crclbar. is an inert neutralizing anion. The isothiouronium salts are surprisingly effective dispersing agents and are used in forming electrodepositable latexes.

International Classification:

C08F22800
C08F22038

US Classification:

526256

Abstract:

Novel polymers having high activity as cationic surface-active agents are prepared by the addition polymerization of ethylenically unsaturated aromatic sulfonium salts, e. g. , ##STR1## When such polymers are heated and/or dried, they are irreversibly converted to inert, nonionic residues without the elimination of odorous by-products. The novel sulfonium salt polymers having relatively low molecular weight and low charge density are particularly useful as surfactants or emulsifiers in the emulsion polymerization of ethylenically unsaturated monomers such as styrene, butadiene, alkyl acrylates and the like. The polymers having high molecular weight and high charge density are useful as thickeners and flocculants.

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

C08L 6300

US Classification:

260 292EP

Abstract:

Modified cationic latexes are prepared from nonionic or cationic latexes having particles containing chemically bound epoxide groups at or near the particle surface by reacting the latex with a nucleophile such as dimethyl sulfide and an acid such as acetic acid to form a latex having stabilizing onium ions chemically bound to the particle at or near the particle surface.

Inventors:

Christian T. Goralski - Midland MI
Thomas C. Klingler - Midland MI

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

C07D29522

US Classification:

2602471R

Abstract:

The compounds of the formula ##SPC1## In which R is lower alkyl, lower alkoxy or halo, x is an integer from 0 to 2, n is an integer from 0 to 3, Y is halo and R. sub. 1 and R. sub. 2 independently are hydrogen, lower alkyl, phenyl or substituted phenyl, or, together with the nitrogen atom, form a heterocyclic ring also containing up to one oxygen atom in the heterocycle. The compounds in which x is 0 are prepared by adding chlorine or bromine to a 1-arylthiomethanesulfonamide in the presence of pyridine to form the 1-arylthio-1, 1-dihalomethanesulfonamide. The compounds in which x is 1 or 2 is prepared by adding sodium hypochlorite or sodium hypobromite to a 1-(arylsulfinyl)methane-sulfonamide or a 1-(arylsulfonyl)methanesulfonamide to form the 1-(arylsulfinyl)-1,1-dihalomethanesulfonamide or 1-(arylsulfonyl)-1,1-dihalomethanesulfonamide, respectively. The compounds are useful as antimicrobial agents.

Abstract:

Compounds of the formula ##STR1## wherein: EACH R individually is H, OH or C. sub. 1 -C. sub. 4 alkoxy; Each R' individually is H or C. sub. 1 -C. sub. 4 alkyl, and a is 1 or 2; Each sulfur is ortho or para to a phenolic oxygen; x is 0 or a positive number; y is 0 or a positive number; Z is a bridging group of the formula: (1) --O--, --S--, --O(C. sub. m H. sub. 2m)O-- where m is 1-6, and. SIGMA. (x+y)=1; (2) --CR". sub. 2 -- where R" is C. sub. 1 -C. sub. 4 alkyl, and. SIGMA. (x+y)=1; or (3) --CH. sub. 2 -- and. SIGMA. (x+y)=1-20; Are produced in the process comprising the steps of: (a) reacting chlorine or sulfuryl chloride with a solution comprising a cyclic polymethylene sulfide (e. g. thiophane), iodine and HCl dissolved in liquid sulfur dioxide, thus forming a chlorine complex of the cyclic sulfide; and (b) reacting the chlorine complex from step (a) with the appropriate phenol in liquid sulfur dioxide.
