Krzysztof  Matyjaszewski (pronounced Ma-ti-ya-shev-ski), Professor of
Chemistry at Carnegie Mellon University, will receive the 1994 Carl S.
Marvel Creative Polymer Chemistry Award of the ACS Division of Polymer
Chemistry, sponsored by the Dow Chemical Company Foundation.
Matyjaszewski is recognized for his innovative work on the synthesis of
precisely defined organic and inorganic polymers.

Matyjaszewski received the Ph.D. (1976) and Habilitation (1985) degrees
from the Polish Academy of Sciences, and carried out postdoctoral work
at the University of Paris and the University of Florida.  His early
work focused on cationic ring-opening polymerization of heterocyclics,
including cyclic ethers, orthoesters, sulfides, iminoethers, and amines
in careful, systematic explorations that became a hallmark of his
subsequent endeavors.

After joining Carnegie Mellon in 1985, Matyjaszewski concentrated on
the synthesis of novel organometallic and inorganic polymers,
particularly polysilanes and polyphosphazenes, and control of structure
in the synthesis of organic polymers.  His studies of polysilanes led to
new preparative methods: a low -temperature sonochemical reductive
coupling, modification of polysilanes with aryl groups via
protodesilylation, preparation of the first chiral polysilanes and a
ring-opening polymerization of strained cyclopolysilanes. The latter
method provided the first polysilanes with controlled microstructure and
enabled control of molecular weight, polydispersity and the preparation
of block copolymers.  He also discovered a new and more efficient
synthetic route to polyphosphazenes, based on anionic polymerization of
phosphoranimines.  The process provides quantitatively linear
polyphosphazenes with narrow molecular weight distributions under mild
conditions, and has made possible the first copolymers with two
different polyphosphazene segments. Another approach based on
polymerization of phosphine azides provided the first soluble
poly(diarylphosphazenes).

The thrust of Matyjaszewski's current research is the synthesis of well
defined polymers and copolymers by carbocationic and radical
polymerization . He has critically evaluated and applied the concept of
living polymerization to these systems, and elucidated the reaction
mechanism, involving a rapid reversible deactivation of growing species
present in minute amounts. The new initiation systems for radical and
carbocationic processes provide  polymers and copolymers with novel and
controlled structures and topologies.

As chairman of the Polymer Currriculum Development Award Committee of
the ACS Polymer Division, Matyjaszewski has been deeply involved in
efforts to promote innovative projects in polymer education and to
disseminate the experience and curriculum materials that they generate.
He has received a Presidential Young Investigator Award (1989), and
awards from the Polish Academy of Sciences (1981) and the Polish
Chemical Society (1980).  He is a member of several editorial boards and
serves on the  IUPAC Nomenclature Committee.
