Title:
GRAFT MODIFIED ETHYLENE POLYMER
Document Type and Number:
Japanese Patent JP3483171
Kind Code:
B2
Abstract:
PURPOSE: To obtain a graft modified ethylene polymer excellent in adhesion to a metal or a polar resin by grafting a polar monomer onto an ethylene polymer having specified physical properties (e.g. melt flow rate).
CONSTITUTION: This graft modified ethylene polymer is produced by grafting 0.1-50wt.% polar monomer (e.g. an ethylenically unsatd. monomer having a hydroxyl, amino, or epoxy group, an arom. vinyl, or a vinyl chloride) onto an ethylene homopolymer or ethylene/3-20C α-olefin copolymer having an ethylene content of 50-100wt.%, a density of 0.85-0.98g/cm3, a melt flow rate(MFR) which is 0.01-200g/10min at 190°C under a load of 2.16kg and satisfies the relation with the melt tension (MT) as expressed by formula I, an index of mol.wt. distribution Mw/Mn (wherein Mw is the wt. average mol.wt.; and Mn is the number average mol.wt.) of 2.5 or lower, and a temp. (Tm °C) at the max. peak in the endothermic curve obtd. with a differential scanning calorimeter satisfying the relation with the density (d) as expressed by formula II.
