The December GGPF lecture will be given by U.C. Berkeley's Prof.
Nitash P. Balsara. Prof. Balsara spoke earlier this year at the Stanford
Flory Symposium, and the GGPF is pleased to host him for this presentation. Please come to meet Prof. Balsara and hear about some excellent work in the area of polymer blends.


DECEMBER GGPF Dinner Lecture:

Tuesday, Dec. 11
Michael's at Shoreline
Mountain View


Prof. Nitash P. Balsara
Chemical Engineering Department
University of California, Berkeley


Mixtures of highly incompatible A/B homopolymers were
organized into microemulsions and lamellar phases by
the introduction of a suitably designed A-C diblock
copolymer. This is a significant departure from the
large body of previous experimental and theoretical
work in the field of polymer blends, which relied on
the surfactancy of A-B block (and graft) copolymers
for organizing A/B mixtures. We use small angle
neutron scattering to demonstrate that 50/50 mixtures
of highly immiscible polyolefins such as polyisobutylene
(PIB), polyethylene (PE) can be organized into
microemulsions and lamellar phases by the addition of
a symmetric polyethylene-block-head-to-head polypropylene copolymer (PE-PP). Along the isopleth, the phase diagram of these ternary blends exhibits many of the characteristics of "fish-shaped" phase diagrams found in oil/water mixtures stabilized by surfactants with balanced hydrophobic and hydrophilic tendencies. We thus believe that our observations in PIB/PE/PE-PP mixtures are due to the balance between PIB-philic and PIB-phobic tendencies of our PE-PP surfactant. Our work demonstrates a pathway for designing balanced surfactants in systems such as hydrocarbon polymer mixtures wherein specific interactions and permanent dipoles are absent.

Speaker Background:

Nitash P. Balsara was born and raised in Bombay. He went to the Indian Institute ofTechnology at Kanpur where he graduated with a bachelors degree in Chemical Engineering in 1982. He earned a PhD in Chemical Engineering at Rensselaer Polytechnic Institute in Troy, New York in 1988. He did post-doctoral research at the Department of Chemical Engineering and Materials Science at the University of Minnesota, and at Exxon Research and Engineering Company in Annandale, New Jersey. In 1992, he oined the Department of Chemical Engineering at Polytechnic University in Brooklyn, New York. He moved to the University of California, Berkeley in 2000 where he is currently a professor of Chemical Engineering. His research is concerned with nanostructure formation and phase transitions in polymer materials. He received the National Science Foundation Young Investigator Award, the John H. Dillon Medal for Polymer Physics, from the American Physical Society, and the Camille Dreyfus Teacher- Scholar Award.
