MALLINCKRODT SELLS ADDITIVE PREBLEND BUSINESS
TO CIBA SPECIALTY CHEMICALS

     ST. LOUIS, Missouri, October 17, 1997   Ciba Specialty Chemicals
Inc. (SWX:CIBN) has purchased the additive preblend business of
Mallinckrodt Inc. (NYSE:MKG), the companies announced today.  Terms
of the agreement were not disclosed.
     Mallinckrodt is a leader in the production of additive preblends
in pellet form for the polymers industry.  Additives are ingredients
added in small quantities to materials such as polymers.  They lead
to improved durability, quality and appearance of finished goods.
     "Mallinckrodt's expertise in customer service and technology
complements Ciba's know-how in the area of polymer stabilizers. 
Combined they will allow a new standard of product breadth, service
and responsiveness," said Reinhard Neubeck, president of the Global
Additives Division.
     Daniel E. Woods, Jr., president of Mallinckrodt's Catalysts &
Chemical Additives Division, said:  "Mallinckrodt has developed a
strong expertise in polymer preblends, but Ciba is better established
overall in the additives business.  We believe our customers and our
employees are best served by the sale of this portion of our business
to Ciba, and we look forward to their continued success."
     The Additives division is part of Ciba Specialty Chemicals, a
global leader in the discovery, development and manufacture of
innovative materials that provide color, performance and care for
plastics, coatings, fibers, fabrics and other products.  The five
divisions " Additives, Consumer Care, Performance Polymers, Pigments

markets.  Ciba Specialty Chemicals had 1996 global sales of more than
CHF 6.7 billion.

markets worldwide.  The company has four major businesses -
pharmaceuticals, diagnostic imaging, respiratory care and specialty
chemicals.  The St. Louis, Missouri-based company, with fiscal 1997
