Title: Study on synthesis and properties of polybutiene based liquefaction modified MDI of different hard segment structure
Abstract: Using hydroxyl terminated polybutadiene as prepolymer, Liquefaction modified 4,4′ methylenebis (phenyl isocyanate) as cross linking agent, BD and ED as chain extenders. We synthesized polybutadiene-based polyurethane elastomer of different hard segment structure. The effet of the kinds and amounts of chain extender on the physical properties of the elastomer was studied. The break surface was studied by using SEM also.
