For the seventh time, BASF Aktiengesellschaft, Ludwigshafen, Germany, has presented its Innovation Award for new in-house developments
and their successful implementation. The winners are polyvinylamine, a new class of process chemicals which enables paper to be produced
more easily and in better quality, and a fast and highly efficient synthetic route to the UV-B absorber Uvinul MC 80.
The award, which BASF has presented annually since 1993 to the best in-house innovation,
carries a total prize of DM 140,000 (about EUR 72,000).
"Innovations are intelligent products, processes and concepts which will shape our future. They are only possible through excellent teamwork
and outstanding commitment by all participants", said Dr. Stefan Marcinowski, member of BASF's Board of Executive Directors and Research
Executive Director. Many developments which have won the Innovation Award in the past have become success stories for BASF, he added.
In 1999 alone, the award-winning projects since 1993 resulted in sales of more than EUR 700 million for the company - and the trend is
A six-person team from Ludwigshafen won the award for the development of polyvinylamine: Dr. Jacques Dupuis, Dr. Friedrich Linhart, Dr.
Primoz Lorencak, Dr. Martin Rübenacker, Dr. Andreas Stange and Manfred Winter increased the range of BASF paper chemicals with a
product which makes paper more difficult to tear and also allows it to be more cheaply and with fewer production stoppages. By 2005, BASF
expects annual sales of around 100 million Euro.
Dr. Michael Hüllmann and Dr. Christof Kandzia, also from BASF Aktiengesellschaft in Ludwigshafen, discovered a completely new process
for the production of the UV absorber Uvinul MC 80. Their route is a "shortcut" of the conventional synthesis and it also gives a purer product.
The low production costs mean an enormous competitive advantage. Uvinul MC 80 has consequently been a rapid market success - and is
continuing to grow.
All-rounder makes paper more tear resistant and cheaper
From newspapers to teabags, from art prints to labels - our lives would be hard to imagine
without paper. 300 million metric tons per year are produced worldwide. The everyday product is
produced from chemical pulp, wood pulp and additives, such as starch, fillers, such as chalk or
china clay, as well as increasingly also recycled paper. These ingredients are pulped with water,
and the water is removed by sieving, drying and pressing in papermaking machines, some of
which are enormous. At the end, the machines produce finished paper webs at a speed of 100
kilometers per hour. For the process to function properly, small amounts of cationic, i.e. positively
charged, paper chemicals must be added to the stock. These products also keep the process
water removed from the paper free from disturbing substances, for example tree resins or traces of
adhesive from the recycled paper. This enables the water to be recycled in a closed circuit.
The paper chemicals used today are primarily linear polyacrylamides and highly branched
polyethyleneimines. The former ensure that sufficient starting materials remain on the wire and
that a paper web forms rapidly, while the latter have a similar effect and remove from the raw
materials substances which would
