Fast Molecular Rearrangements Hold Key to Plastic's Toughness
November 27, 2008
In a University of Wisconsin-Madison study appearing November 28 in Science Express, researchers report that subjecting a common plastic to physical stress--which causes the plastic to flow--also dramatically increases the motion of the material's constituent molecules, with molecular rearrangements occurring up to 1,000 times faster than without the stress.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
