Jun 20, 1995
Appl. No.:

8/492627
Inventors:

Lawrence R. Brecker - Armonk NY
Radu Bacaloglu - Hamburg NJ

Assignee:

Witco Corporation - Greenwich CT
International Classification:

C23F 1112
C23F 1118
US Classification:

25240052
Abstract:

An overbased mixture of aliphatic and aromatic carboxylates salts useful in making low-fogging thermal stabilizers for PVC is made by reacting zinc oxide with fatty acid and such as stearic acid, then adding aromatic acids, and then adding and reacting one or both of magnesium oxide and calcium oxide, under controlled heating conditions to maintain fluidity while minimizing side reactions, and then conditioning the reaction product to remove volatiles.

Filed:

May 2, 1997
Appl. No.:

8/850689
Inventors:

Michael A. Croce - Oakland NJ

Otto Loeffler - Colts Neck NJ
Assignee:

Witco Corporation - Greenwich CT
International Classification:

C08K 551
US Classification:

524 15
Abstract:

Disclosed is a stabilizer composition effective to protect PVC resin against heat-mediated deterioration, comprising a mixture of barium and zinc salts of aliphatic C. sub. 6 -C. sub. 20 carboxylates and aromatic C. sub. 7 -C. sub. 12 carboxylates, organic triphosphites of the formula R. sub. 1 OP(OR. sub. 3)OR. sub. 2 wherein each of R. sub. 1, R. sub. 2 and R. sub. 3 is C. sub. 6 -C. sub. 12 alkyl or phenyl, and organic acid phosphites of the formula R. sub. 4 OP(OH)OR. sub. 5 wherein each of R. sub. 4 and R. sub. 5 is C. sub. 6 -C. sub. 12 alkyl or phenyl, or R. sub. 4 can be hydrogen. PVC film compounded with this stabilizer composition also exhibits improved wettability and adherence to water-based inks applied to such films.

US Patent:

39351700, Jan 27, 1976
Filed:

Feb 3, 1975
Appl. No.:

5/546794
Inventors:

Otto Ernest Loeffler - Rahway NJ
Assignee:

NL Industries, Inc. - New York NY
International Classification:

C08G 6314
US Classification:

260 75R
Abstract:

A novel antimony catalyst for polyester condensation reactions is described comprising trivalent antimony having its valences occupied by dianion radicals of 1,2-diols and anion radicals or organic carboxylic acids. The molar ratio of antimony to dianion radical of 1,2-diol to anion radical of organic carboxylic acid is 1:1:1. The antimony compound is prepared by reacting a mixture of a 1,2-diol and a trivalent antimony reactant represented by the formula; ##EQU1## wherein Sb is antimony, R. sub. 1 is an anion radical of an organic carboxylic acid; and R. sub. 2 is selected from the group consisting of anions of alcohols, anions of organic carboxylic acids and mixtures thereof.

US Classification:

252313R
Abstract:

An aqueous stabilized antimony pentoxide sol composition, comprising from 25% to 35% antimony pentoxide, from 6. 5% to 17% of an amine and the remainder water, has been prepared. A dried composition obtained from this sol composition has also been prepared. The dried powder contains from 62% to 76% antimony pentoxide, from 17% to 32% of an amine and the remainder absorbed and combined water. This dried composition when added to water or an organic solvent readily forms the stabilized sol composition originally obtained.
