Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
67 words
A perfluoroalkyl-substituted polyisocyanate comprising the product prepared by the sequential reaction of a polyisocyanate containing two or more reactive isocyanate groups per molecule with a terminally unsaturated alkenyl or alkynyl Zerwitinoff hydrogen-containing compound, perfluoro-alkylating the resulting alkenylated or alkynylated polyisocyanate by reaction with perfluoroalkyl iodides at a pH between 2 and 8, and dehydroiodinating the resulting perfluoroalkyl-substitured polyisocyanate so as to effect elimination of hydrogen iodide therefrom.
Claim 2
Dependent Claim
67 words
A perfluoroalkyl-substituted polyisocyanate comprising the product prepared by the sequential reaction of a polyisocyanate containing two or more reactive isocyanate groups per molecule with a terminally unsaturated alkenyl or alkynyl Zerwitinoff hydrogen-containing compound, perfluoro-alkylating the resulting alkenylated or alkynylated polyisocyanate by reaction with perfluoroalkyl iodides at a pH between 2 and 8, and dehydroiodinating the resulting perfluoroalkyl-substitured polyisocyanate so as to effect elimination of hydrogen iodide therefrom.
Claim 3
Dependent Claim
38 words
The perfluoroalkyl-substituted polyisocyanate of claim 1 wherein said polyisocyanate containing two or more reactive isocyanate groups per molecule comprises a hexamethylene diisocyanate homopolymer having the formula: ##STR8## wherein x is an integer equal to or greater than 1.
Claim 4
Dependent Claim
