HIGHLY FLOWABLE 1-BUTENE POLYMER AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A 1-butene polymer satisfying the following (1), (2) and either (3) or (3'): a process for producing the polymer; a resin modifier comprising the polymer; and a hot-melt adhesive containing the polymer. (1) The intrinsic viscosity Ä eta Ü as measured in tetralin solvent at 135 DEG C is 0.01 to 0.5 dL/g. (2) The polymer is a crystalline resin having a melting point (Tm -D) of 0 to 100 DEG C, the melting point being defined as the top of the peak observed on the highest-temperature side in a melting endothermic curve obtained with a differential scanning calorimeter (DSC) in a test in which a sample is held in a nitrogen atmosphere at -10 DEG C for 5 min and then heated at a rate of 10 DEG C/min. (3) The stereoregularity index ä(mmmm)/(mmrr + rmmr)ü is 30 or lower. (3') The mesopentad content (mmmm) determined from a nuclear magnetic resonance (NMR) spectrum is 68 to 73%. |
