Metallocenes
â– It took almost 15 years for metallocenes to leave the laboratory. Today, these polyolefin polymerisation catalysts are used to make polymers with unique properties.
Initially used with polyethylene (PE), the applications of metallocene catalysts have extended to other polymer materials, from thermoplastics to elastomers, including plastomers. Recent studies confirm the interest in these polymers produced using metallocene catalysts. By the end of 1998, 1.3 million tonnes of metallocene polyolefins should be produced in North America, 750,000 tonnes in Europe and 400,000 tonnes in Japan. Global consumption is set to multiply by six by 2001. Metallocene polymers are now being used in stretch wrap and shrink film, films for food or agricultural use, medical pouches and electric cable sheaths. Other uses are being developed: piping, seals and a number of injected or rotomoulded products. But these new materials need time to find their place on markets that have economic constraints.
The survey provides an update on the chemistry of metallocenes and reviews the offer of manufacturers, describing the advantages and limits of available materials. The different uses of polymers are explained and discussed. An analysis of the latest patents and research projects in progress is made and will allow readers to anticipate future changes.
A list of addresses and a number of bibliographical references completes the survey.
