A process for preparing a curing composition of a coordination complex comprising methylenedianiline (MDA) and a salt, and less than 1000 of free MDA. The curing composition may be used in curing polyurethanes and epoxy resins.

Curing compositions having low-free amounts of methylenedianiline

A curing composition of a coordination complex comprising methylenedianiline (MDA) and a salt, and less than 1000 of free MDA. The curing composition may be used in curing polyurethanes and epoxy resins.

An alkyltin compound of specified formula which has utility as an excellent stabilizer for a halogen-containing resin. The alkyltin compound has from 1-3 terminal thiol groups.

Alkyltin sulfanyl mercaptocarboxylates having terminal thiol groups

A method is disclosed for stabilizing a halogen-containing polymer wherein the method comprises adding to said polymer a thermally stabilizing amount of a mixture comprising at least one polyalkylene glycol and at least one metal salt of a strong acid selected from the group consisting of perchloric acid, trifluoroacetic acid, trifluoromethanesulfonic acid, alkylsulfuric acid, phosphotungstic acid, HPF, HBF, and HSbF.

Stabilization system for halogen-containing polymers

Heterocyclic tin compounds, useful as flame retardants and/or as smoke suppressants for halogen-containing polymers, e.g., polyvinyl chloride resins having application as wire and cable coatings, are obtained by reacting a trisubstituted triazine such as melamine with a tin-containing compound such as tin tetrachloride.

Heterocyclic tin flame retardants/smoke suppressants and halogen-containing polymer composition containing same

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.
