Filed: 1994-07-07
Abstract: PURPOSE:To improve the resistances to heat and shear of polydioxolane and enable it to be produced and molded stably by adding a hindered phenol compd. having a specified mol.wt. and a structure to it. CONSTITUTION:Polydioxolane is stabilized by adding to it at least either a compd. having a mol.wt. of 500 or higher and at least two hindered phenol groups in the molecule (A) or a compd. having a mol.wt. of 500 or higher and at least one hindered phenol group and at least one hindered amine group in the molecule (B).
