  • MOULDABLE, BIODEGRADABLE MATERIAL
    Publication number: 20100113642
    Abstract: A mouldable, biodegradable medical material, comprising an epsilon caprolactone homopolymer. The material is useful as an implant and in particular for filling irregularly shaped cavities in biological tissue in vivo. The epsilon caprolactone homopolymer can be produced by polymerizing epsilon caprolactone monomers in the presence of a titanium alkoxide catalyst.

  • Metallocene compounds for the polymerization of ethylenically unsaturated monomers
    Patent number: 6362356
    Abstract: The invention relates to metallocen compounds having &eegr;5 ligands comprising at least four fused rings and having a sum of fused rings in all of its &eegr;5 ligands being at least 6. Such compounds are for example {[1-(7,9-diphenylcyclopent[a]acenaphthadienyle)-1-phenyle-2-(7,9-diphenylcyclopent[a]acenaphthadienyl)]ethane} zirconium dichloride, {[1-(7,9-diphenycyclopent[a]acenaphthadienyl)-1-phenyl-2-flourenyl]ethane} zirconium dichloride, [bis(7,9-diphenylcyclopent[a]acenaphthadienyl)] zirconium dichloride and [bis(7,9-diphenylcyclopent[a]acenaphthadienyl)]hafnium dichloride. The invention also relates to a catalyst composition comprising such as an aluminoxane. The metallocene compound and the catalyst composition can successfully be used to produce high molecular weight polyethene and long-chain branch polypropene.
