Disclosed herein is a process for improving mechanical properties and thermal stability of composites of poly(vinyl chloride) and at least one natural fiber comprising including in said composite an agent comprising a polymer or copolymer comprising at least one alkali metal salt of at least one polymerized ethylenically unsaturated carboxylic acid. Articles of manufacture comprising the stabilized PVC are also disclosed.

Wood sizing agents for PVC composites

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

Metal salts of organic acids complexed with &#x3b2;-diketone compounds are multifunctional complexes useful in the formulation of stabilizers for halogenated resins. These complexes may be used jointly with other low toxicity intermediates, such as zinc or magnesium intermediates, to form effective stabilizers that are non-toxic and exhibit better performance than other known stabilizers, including those containing toxic heavy metals such as cadmium or lead. The complex is prepared utilizing a Claisen condensation reaction and precipitation with water and heptane.

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.

Process for base-promoted condensation reactions and base reagent therefor

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.
