Abstract:Polyurethane ( PU ) elastomers were synthesized from polyether diol, polytetramethylene-oxide glycol (PTMEG) and polypropylene glycol (PPG) as a soft segment,different isomer methylenebis (phenyl isocyanate) (MDI-50,MDI-100LL),and chain extender,tri(hydroxymethyl) propane (TMP) and 1,4-butanediol (BDO) as a hard segment by two-step bulk polymerization process. The mechanical properties and loss tangent ( tan δ) of the PU elastomers were investigated.
Keywords:polyurethane  mechanical property  damping property
