The melt strength and the melt index ratio of ethylene-based polyolefins are controlled by the lower alkyl substitution pattern of the bridged cyclopentadienyl ligands of metallocene polymerization catalyst precursor compounds.
Dans cette invention, la résistance à la fusion et le rapport des indices de fusion de polyoléfines à base d'éthylène sont régulés par le modèle de substitution à alkyle inférieur des ligands cyclopentadiényle pontés de composés précurseurs de catalyseurs de polymérisation de métallocènes.
