WebJul 29, 2024 · Polyethylene- graft - i PP copolymers (PE- g - i PP) were prepared using a grafting-through strategy by copolymerization of ethylene with allyl-terminated i PP macromonomers in the presence of a hafnium pyridylamido catalyst. Graft copolymers with a variety of graft lengths ( Mn = 6–28 kg/mol), graft numbers, and graft spacings were … Isopentenyl pyrophosphate (IPP, isopentenyl diphosphate, or IDP) is an isoprenoid precursor. IPP is an intermediate in the classical, HMG-CoA reductase pathway (commonly called the mevalonate pathway) and in the non-mevalonate MEP pathway of isoprenoid precursor biosynthesis. Isoprenoid precursors such as IPP, and its isomer DMAPP, are used by organisms in the biosynthesis of terpenes and terpenoids.
