Abstract | Provided is a branched propylene-based polymer which retains a melt tension necessary for molding and has excellent spreadability during melting. The branched propylene-based polymer comprises propylene and 0-11 mol% ethylene and α-olefin having four or more carbon atoms and has the following properties (1) to (4). (1) An MFR of 0.1-100 g/10 min. (2) An Mz/Mw of 2.5-4.0. (3) A branching index g' (1,000,000) of 0.60-0.75. (4) The flow activation energy (Ea), kJ/mol, obtained through a dynamic viscoelasticity measurement and the MFR satisfy the following relationship (1). Relationship (1): Ea≥-12.5×log(MFR)+66
L'invention concerne un polymère ramifié à base de propylène qui conserve la tension de fusion nécessaire au moulage et présente néanmoins une excellente aptitude à l'étalement pendant la fusion. Le polymère ramifié à base de propylène comprend du propylène et de 0 à 11 % en moles d'éthylène et d'α-oléfine ayant quatre atomes de carbone ou plus et comprend les propriétés (1) à (4) suivantes. (1) Un MFR de 0,1 à 100 g/10 min. (2) Un Mz/Mw de 2,5 à 4,0. (3) Un indice de ramification g' (1 000 000) de 0,60 à 0,75. (4) L'énergie d'activation de flux (Ea), kJ/mol, obtenue par une mesure de viscoélasticité dynamique et le MFR satisfont la relation suivante (1). Relation (1) : Ea ≥ -12,5 × log(MFR) + 66
成形加工に必要な溶融張力を保持しながら、溶融時の延展性に優れる分岐状プロピレン系重合体を提供する。 プロピレンと、エチレン及び炭素数4以上のαオレフィン0~11mol%からなる分岐状プロピレン系重合体であって、下記特性(1)~(4)を有する、分岐状プロピレン系重合体。特性(1):MFRが0.1g/10分~100g/10分である;特性(2):Mz/Mwが2.5~4.0である;特性(3):分岐指数g'(100万)が0.60~0.75である;特性(4):動的粘弾性を測定して得られる流動活性化エネルギー(Ea)kJ/molとMFRとが下記の式(1)を満たす。[式(1):Ea≧-12.5×log(MFR)+66] |
