Title:
PROPYLENE POLYMER COMPOSITION AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH05222138
Kind Code:
A
Abstract:
PURPOSE:To obtain the title composition which can provide a molding excellent in coatability by specifying the structural state of the title composition prepared by modifying a polymer composition comprising a propylene polymer and an amorphous ethylen/propylene copolymer with a specified modifier. CONSTITUTION:The title composition is prepared by modifying an unmodified propylene polymer composition comprising 20-99 pts.wt. propylene polymer (e.g. PP) of a melt flow rate(MFR) of 0.1-30g/10min and 1-80 pts.wt. amorphous ethylene/propylene copolymer of an MFR of 0.1-10g/10min with at least one modifier selected between an ethylenically unsaturated compound containing a tert. amino group and an ethylenically unsaturated compound containing an epoxy group (e.g. N,N-dimethylaminoethyl acrylate) so that the modified ethylene/propylene copolymer is present in a state dispersed in the modified propylene polymer, and the mean particle diameter of the dispersed particles may be 5mum or below.
