SOLVENT BORNE POLYURETHANE PROCESS |
摘要 |
A process for obtaining a solvent borne polyurethane composition comprising preparing an isocyanate-terminated prepolymer A; reacting the isocyanate groups of isocyanate-terminated prepolymer A with 0.1 to 1.8 stoichiometric equivalents of at least one active-hydrogen containing chain-terminating compound and or chain-extending compound; optionally introducing an isocyanate-terminated compound B; and reacting the isocyanate groups of the isocyanate-terminated prepolymer obtained in the previous steps and isocyanate-terminated compound B with 0 to 1.2 stoichiometric equivalents of at least one active-hydrogen containing chain-terminating compound and or chain-extending compound.
