Abstract
(EN)
The present invention relates to an olefin-based polymer meeting the requirements that (1) the melt index (MI, a condition of 190°C and a load of 2.16 kg) is 0.1-10.0 g/10 min, (2) the melting temperature in differential scanning calorimetry (DSC) measurement is 20-70°C, (3) a high-temperature melting peak is identified at 75-150°C in DSC successive self-nucleation annealing (SSA) measurement, and the sum of the enthalpy of fusion ΔH(75) in the corresponding area is 1.0 J/g or more. The olefin-based polymer according to the present invention is a low-density olefin-based polymer, and has a highly crystalline region introduced therein, thereby exhibiting a high mechanical stiffness.
(FR)
La présente invention concerne un polymère à base d'oléfine répondant aux exigences selon lesquelles (1) l'indice de fluidité (MI, dans une condition de 190 °C et avec une charge de 2,16 kg) est de 0,1 à 10,0 g/10 min, (2) la température de fusion dans une mesure par calorimétrie différentielle à balayage (DSC) est de 20 à 70 °C, (3) un pic de fusion à haute température est identifié à 75 à 150 °C dans une mesure de recuit à auto-nucléations successives (SSA), et la somme de l'enthalpie de fusion ΔH(75) dans la zone correspondante est supérieure ou égale à 1,0 J/g. Le polymère à base d'oléfine selon la présente invention est un polymère à base d'oléfine de faible densité, et possède une région hautement cristalline introduite en son sein, d'où une grande rigidité mécanique.
