Title:
イソシアネートフリー及びイソチオシアネートフリーのアルコキシシランポリマーの製造のための反応体としての有機カーボネート変性プレポリマーの使用
Document Type and Number:
Japanese Patent JP7219708
Kind Code:
B2
Abstract:
The use of an organocarbonate-modified prepolymer having at least an average of 1.5 carbonate, thiocarbonate, carbamate or thiocarbamate groups bonded directly to the polymer backbone each via an oxygen atom, where each of these oxygen atoms has its origin in the reaction of a primary, secondary or tertiary hydroxyl group of the polymer backbone and a reactive compound selected from the group consisting of a diorganocarbonate, a diorganothiocarbonate, a cyclic carbonate, a cyclic thiocarbonate, an N,N-diheterocyclourea derivative and an N,N-diheterocyclothiourea derivative. Also, the preparation of the alkoxysilane polymers.
