Process For Curing Olefin Polymers

View page
US Patent:
39741320, Aug 10, 1976
Filed:
May 15, 1975
Appl. No.:
5/577585
Inventors:
Leo L. Valdiserri - Washington WV
Assignee:
Borg-Warner Corporation - Chicago IL
International Classification:
C08F 840
C08K 549
US Classification:
526 20
Abstract:
Heat-curable ethylene polymer compositions wherein triallyl phosphate is used as a coagent. The composition also contains an organic peroxide catalyst.

Process For Preparing Phosphite-Isocyanurates Oligomers

View page
US Patent:
45461805, Oct 8, 1985
Filed:
Apr 19, 1983
Appl. No.:
6/486476
Inventors:
Leo L. Valdiserri - Belpre OH
Richard P. Woodbury - Belpre OH
Assignee:
Borg-Warner Chemicals, Inc. - Parkersburg WV
International Classification:
C07D40312
C07D40314
US Classification:
544214
Abstract:
A process for preparing certain phosphite-isocyanurate oligomers. The process requires the reaction of a trishydroxyalkyl isocyanurate with a tris-organophosphite and, optionally, an alcohol or alkylphenol. The process is promoted by an alkaline catalyst such as sodium methoxide. The oligomeric product is useful as a thermal stabilizer in polymer compositions.

Oligomeric Aromatic Polyphosphites

US Patent:
44130775, Nov 1, 1983
Filed:
Jun 22, 1981
Appl. No.:
6/275575
Inventors:
Leo L. Valdiserri - Belpre OH
Assignee:
Borg-Warner Chemicals, Inc. - Parkersburg WV
International Classification:
C07F 915
C08K 552
US Classification:
524120
Abstract:
Aromatic, phenol-free polyphosphites containing at least two pentaerythritol residues and three bis-phenolic residues. They are effective polymer additives and are especially useful in enhancing the thermal stability of polypropylene.

Organic Phosphite Ester Compositions Containing Hindered Piperdinyl Light Stabilizers

View page
US Patent:
53429788, Aug 30, 1994
Filed:
May 24, 1993
Appl. No.:
8/066695
Inventors:
William P. Enlow - Belpre OH
Leo L. Valdiserri - Roswell GA
Assignee:
General Electric Company - Pittsfield MA
International Classification:
C07F 902
US Classification:
554 78
Abstract:
Hydrolytically stabilized phosphite compositions are provided. The compositions contain an organic phosphite ester antioxidant and a hindered piperidinyl light stabilizer. The hindered piperidinyl component is not only a light stabilizer but also functions to hydrolitically stabilize the organic phosphite antioxidant. The compositions are useful as stabilizer additives to polymeric compositions.

US Patent:
42061113, Jun 3, 1980
Filed:
Aug 10, 1978
Appl. No.:
5/932885
Inventors:
Leo L. Valdiserri - Belpre OH
Elyse M. Bullock - Parkersburg WV
Assignee:
Borg-Warner Corporation - Chicago IL
International Classification:
C08K 513
C08K 534
C08K 552
US Classification:
260 458NT
Abstract:
An ultraviolet stabilizer for olefin polymers. It is a combination of a 2-hydroxyphenylbenzotriazole, a dialkyl pentaerythritol diphosphite and a phenolic ester oxidation inhibitor.

Phosphite-Isocyanurates

View page
US Patent:
42873398, Sep 1, 1981
Filed:
Feb 29, 1980
Appl. No.:
6/126142
Inventors:
Leo L. Valdiserri - Belpre OH
Assignee:
Borg-Warner Corporation - Chicago IL
International Classification:
C07D25134
US Classification:
544214
Abstract:
This invention of the present application relates to the stabilizing component in the stabilization of olefin polymers, especially polypropylene during processing, i. e. , at elevated temperatures. The stabilizing component is a phosphite-isocyanurate compound having the structural formula: ##STR1## wherein R is a hydrocarbon radical and R. sup. 1 is methyl or hydrogen.
