Abstract
[Object] To improve heat stability of diethylzinc which is used for a catalyst of polymerizing, an organic synthetic reaction reagent and a raw materials for providing a zinc film by MOCVD. And to offer the diethylzinc composition being superior in heat stability, even if it handles for a long term a metal zinc particle does not precipitate. [Solving Means] Use a diethylzinc composition added a compound which is added an aromatic compound as an additive which has isopropenyl group bonded as a side chain.
