摘要：
The present invention relates to one kind can isocyanate-functional prepolymers obtain) reaction H- functions initiator compound attacks the petite active H atoms of person Ze Wafu and oxirane compounds and comonomer forms the hydroxyl of prodromic phase bearing, whereinIt includes lactide that the comonomer, which is selected from, glycolide, periodic dicarboxylic acid anhydride and a combination thereof, wherein the installation of comonomer is by counting hydroxyl and polyfunctional isocyanate of the carrying of precursors stage from step a) of the precursor phases bearing hydroxyl and step b) that are copolymerized to polymer chain (one or more) to form isocyanate-functional prepolymers. It include this fabric system that this isocyanate-functional prepolymers and metering system have at least two Room the invention further relates to a kind of production functional prepolymer and fabric adhesive system.
