International Classification:

C08K 5/05
C08K 5/32
C09D 147/00

US Classification:

524236, 524247, 524251, 106 3197

Abstract:

The invention relates to anti-skinning agents containing mixtures of organic compounds (combinations of additives), whereby the organic compounds are selected from the groups of (a) organic hydroxylamines and (b) alkylamines and/or alkyl alkanolamines and also relates to compositions containing the combination, especially oxidatively drying paints or coating compositions and article coated with such oxidatively drying paints or coating compositions.

Appl. No.:

10/353153

Inventors:

Jianfeng Lou - Wayne PA, US

Assignee:

ATOFINA Chemicals, Inc.

International Classification:

C08G063/78

US Classification:

528/275000

Abstract:

Disclosed is an improved promoter system for curing resin compositions based on unsaturated polyesters. The promoter system contains at least one primary promoter which is a metallic compound, such as a cobalt salt, and at least one co-promoter which is an alkyl alkanolamine. Such an alkyl alkanolamine is usually an amino (C-C) alcohol, and it is present at 1-15 mole of amine per mole of equivalent cobalt metal. The use of alkyl alkanolamine reduces the level of the cobalt promoter in curing formulations with no deleterious effects on the curing performance, which leads to reduced color formation in finished products.

Appl. No.:

10/722872

Inventors:

Jianfeng Lou - Wayne PA, US
Daniel Alford - Pottstown PA, US

International Classification:

C08K003/28

US Classification:

524/429000

Abstract:

The present invention relates to a finished resin composition containing (a) an unsaturated polyester, b) a polymerizable monomer, (c) a promoter system, and (d) a composite stabilizer; wherein the composite stabilizer is a hydroxylamine oxide and aromatic antioxidant and, optionally, a hydroxylamine and is present at 0.001-0.5 parts per 100 parts of the finished UPE resin. The stabilizing system improves processing stability by preventing gel-particle formation, improved storage stability of the curing compositions by inhibiting formation of overhead popcorn and suppressing drifts of resin viscosity and gel time.

International Classification:

C08F 242

US Classification:

526 83, 526211

Abstract:

In the process according to the invention for the aqueous suspension polymerization of vinyl chloride, alone or as a mixture with another vinyl monomer, the polymerization initiator comprises at least one compound chosen from dialkyl peroxydicarbonates, peroxy-tert-alkanoates and diacyl peroxides and use is made, as agent for halting the polymerization, of a mono- or disubstituted hydroxylamine. The resins thus obtained exhibit improved color and heat stability.
