Printedonacid-freepaper SpringerispartofSpringerScience+BusinessMedia(www.springer.com) Preface Fifty years after the NobelPrize was awarded toKarl Ziegler andGiulioNattain 1963,thepolymerizationofolefinsbymetallorganiccatalystshasgrowntooneof themostfascinatingareasinacademicandindustrialpolymerscienceandnowhas thelargestuseinpolymerproduction.Zieglerhaddiscovered10yearsearlierthata mixtureoftransitionmetalcompounds,especiallytitaniumchloridesandaluminum alkyls, was able to polymerize ethene by an insertion reaction. This spectacular milestone was expanded a year later when Natta prepared and characterized isotactic polypropylene and introduced stereospecific polymerization. In contrast to the high-pressure ethene polymerization invented in 1935 by ICI (Imperial Chemical Industries, Great Britain), the catalyzed olefin polymerization requires onlylowpressureandlowtemperature. Today, more than 130 million tons of polyolefins are produced worldwide per year, the major part with the help of Ziegler–Natta catalysts. Polyolefins have changed the world! They are not only the polymers with the highest production volume, but they also show an unbroken production increase. Containing only carbonandhydrogenatoms,polyolefinsare sustainablematerials, lightinweight, andofferawidevarietyofproperties.Theproductionrequiresonlyeasilyavailable andnontoxicmonomersandproceedswithalmostnolossesorsidereactions.After theirendofuse,polyolefinscaneasilyberecycledthroughmechanicalprocedures tosimplearticles,bypyrolysistogasandoil,orbyincinerationtoenergy. In recent decades, new generations of catalysts with higher activities and stereospecificitiesandmodernproductionprocesseshavebeeninventedtoproduce a great variety of polyolefins ranging from high density polyethylene (HDPE) to linearlowdensitypolyethylene(LLDPE),highmeltingpolypropylene,highmod- uluspolyolefinfibers,ethene–propenerubber(EPR),ethene–propene–dienemono- merrubber(EPDM).Thechromium-basedPhillipscatalystsopenedthefieldofgas phase polymerization for HDPE. New supported Ziegler–Natta catalysts make it possibletoincreasetheactivity,tocontrolthemorphology,andforpolypropylene toincreasetheisotacticitybyaddingdifferentkindsofdonors. Agreatdevelopmentinthisresearchfieldwasthediscoveryofmetalloceneand othertransitionmetalcomplexesactivatedbymethylaluminoxane.Thesecatalysts v vi Preface are up to 10 times more active than Ziegler–Natta catalysts, are soluble in hydro- carbons,showonlyonetypeofactivesite(singlesitecatalysts),andcaneasilybe modifiedintheirchemicalstructure.Thesepropertiesmakeitpossibletopredictthe properties of the resulting polyolefins very accurately from the knowledge of the structure of the catalyst, and thus to control molecular weight and distribution, comonomer content, and tacticity by careful selection of the appropriate reactor conditions.Thesinglesitecharacterofmetallocene-basedcatalystsleadstoabetter understandingofthemechanismofolefinpolymerizationandtotheintroductionof otherbulkycocatalysts. Thedifferentchaptersinthisbookdealwiththedevelopmentofolefinpolymer- ization 50 years after the pioneering work of Ziegler and Natta. Academic and industrial developments of ethene and propene polymerizations are presented, including short biographies of Ziegler and Natta, research on Phillips catalysts, kinetic and active site measurements, and polyolefin characterization. Review chaptersalsodescribethelatestresultsofolefinhomo-,living-,andcopolymeriza- tions by metallocene and other single site catalysts, such as the synthesis of ansa metallocenes, supported iron catalysts, syndiotactic polypropylene, long chain branchedpolyolefins,andcyclicandfunctionalcopolymers.Remarkableprogress has been achieved in the synthesis of polyolefin nanocomposites by an in-situ polymerization process using clay, layered silicates, carbon fibers, and carbon nanotubesasfillers. I thank all the authors very much for giving their time to write these exciting chapters.

The single-site character of metallocene/MAO or other transition metal/ MAO catalysts leads to a better understanding of the mechanism of olefin polymerization.
