Hexamethylphosphoric triamide, also known as hexaphosphoramide and hexamethylphosphoramide, is prepared by the reaction of dimethylamine and phosphorus oxychloride. It is soluble in polar and non-polar solvents. It can be miscible with commonly used plasticizers such as dioctyl phthalate, dioctyl sebacate, and triphenyl phosphite in any proportion. Its toxicity is similar to that of phosphate esters. Hexamethylphosphoric triamide is a light stabilizer for polyvinyl chloride, which makes the product have excellent outdoor anti-aging performance and excellent weather resistance, so it is known as a high-efficiency weathering agent for polyvinyl chloride. Adding it to ethylene-propylene rubber can improve elasticity and oil resistance. It can also be used as a co-catalyst for propylene bulk polymerization to improve the catalytic efficiency of the main catalyst.
