He was awarded the prize "for contributions to the theories of polymer physics in regard to nucleation, block polymer self-assembly, and polyelectrolytes, in particular, for the application of these theories to experimentally-motivated phenomena." This is considered the highest international prize in the area of polymer physics.
The award recognizes outstanding accomplishment and excellence of contributions in polymer physics research. The prize consists of $10,000, up to $1,500 in travel reimbursement, and a certificate citing the contributions made by the recipient.
This prize was established in 1960 and fully endowed by APS in 2018.
