Abstract
Official abstract text for this publication.
The invention relates to an isocyanate-containing prepolymer obtainable by reacting at least one isocyanate with at least one first compound selected from the group comprising monohydric alcohols, thiols and secondary amines; wherein the ratio of the NCO value of the isocyanate-containing prepolymer, to the OH, SH or NH value, of said monohydric alcohol, thiol or secondary amine respectively ranges from 0.0005 to 1.0000 and wherein said at least one first compound is present in a total amount of at least 40% by weight based on the total weight of the isocyanate-containing prepolymer.
First claim
Opening claim text (preview).
The invention claimed is: 1. An isocyanate-containing prepolymer obtained by reacting at least one polyisocyanate with at least one first compound selected from the group consisting of monohydric alcohols, monohydric thiols and monohydric secondary amines; wherein the ratio of the NCO value of the isocyanate-containing prepolymer to the OH, SH or NH value of said monohydric alcohol, monohydric thiol or monohydric secondary amine ranges from 0.0005:1 to 1.0000:1 and wherein said at…
