Title:
【発明の名称】長鎖分岐を有する重合体及びそれらの製造
Document Type and Number:
Japanese Patent JPH10512600
Kind Code:
A
Abstract:
Copolymers, and processes to make them, are provided which are derived from monomers comprising:a) one mono-olefin having a single Ziegler-Natta polymerizable bond;b) a second monomer having at least one Ziegler-Natta polymerizable bond;c) a third monomer having at least two Ziegler-Natta polymerizable bonds such monomer being:i) straight-chained and of less than six or at least seven carbon atoms;ii) other than straight chained; oriii) combinations thereof,such copolymer having:c) at least about one carbon-carbon unsaturated bond per number average molecule;d) viscous energy of activation (Ea) at least 1 kcal/mol greater than a copolymer having a linear backbone derived from same monomers, but excluding species having at least two Ziegler-Natta polymerizable bonds;e) crystallinity level of about 10% to about 50%; andf) Mz/Mw at least about 1.7.Such copolymers show enhanced melt processability and other attributes during end-product fabrication.
