Title:
ポリカルバメート,ポリカルバメートの製造方法,及びポリイソシアネートの製造方法
Document Type and Number:
Japanese Patent JP3833702
Kind Code:
B2
Abstract:
Polycarbamates of a polyisocyanate and secondary alcohols are disclosed. These carbamates are characterized in being readily pyrolyzed to form the corresponding polyisocyanate and alcohol with low formation of tars and other by-products. Thus, these polycarbamates can be pyrolyzed under relatively mild conditions, and in the absence of solvent and catalyst.
