水蒸気吹き込み下におけるポリカプロアミドの解重合

抄録

Depolymerization of polycaproamide was carried out under steam blowing in the presence catalysts: phosphoric acid, potassium dihydrogenphosphate, boric acid and/or sodium hydroxide. The rate of depolymerization of polycaproamide is affected by the acid strength and judging from the data of the amino-end groups contents in the depolymerized polycaproamide, the hydrolysis of amide bond in polycaproamide does not occur 'a result of blowing steam.
