【発明の名称】ポリウレタン分解生成物を加水分解するための方法
Document Type and Number:
Japanese Patent JP2000505125
Kind Code:
A
Abstract:
Process for alcoholizing and hydrolysing a flexible polyurethane foam by bringing a flexible polyurethane foam in contact with an alcoholizing polyol, allowing the foam and the polyol to react in the presence of a catalyst which enhances alcoholysis and hydrolysis of the foam in an amount of 0.001 to 0.25 and preferably 0.001 to 0.08% by weight based on the weight of the foam, then allowing the mixture to separate in an upper phase and a lower phase and collecting these phases in separate containers, wherein the hydrolysis is conducted by adding water and allowing the mixture to react with the water after the foam has been combined with the polyol and before the mixture is allowed to separate.
