Macromolecular Chemistry: The Second Century

The Spring 2020 National Meeting has been postponed to Spring 2021.

American Chemical Society Spring 2020 National Meeting and Expo. March 22-26 in Philadelphia, PA. The theme is Macromolecular Chemistry: the second century.

In 1917, Hermann Staudinger presented his “macromolecular hypothesis” in a lecture on rubber to the Swiss Chemical Society. In 1920, he published “Über Polymerisation”, Ber. Deutsch. Chem. Ges. 1920, 53, 1073. Credited with the term “macromolecules”, he received the Nobel Prize in Chemistry in 1953.

It is difficult to imagine that 100 years ago the concept of long-chain, covalently linked macromolecules was controversial. Today polymer materials are ubiquitous in daily life, from adhesives and fibers to coatings, packaging, and robust plastics. Polymers form the backbone of the US chemical industry and are a vibrant area of research in academe and national labs. At this meeting, we celebrate the preceding century of advances in macromolecular chemistry and take a look at the challenges and opportunities before us.

Funding Opportunities for Technical Sessions

ACS is pleased to offer funds to support collaborative programming at the national meetings. Technical divisions and programming committees are encouraged to apply.  The symposia must be aligned with the national meeting theme and have at least one cooperative cosponsor. Funding is based on the size and duration of each theme-related, cooperatively cosponsored symposium.

The following are provided as examples for planning:

  • $500 per half-day session
  • $1,000 per full-day symposium
  • $2,000 per multi-day symposium

Funds will be paid to the programming group within 30 days following the meeting or credited to the programming group's national meeting bill. Please contact for more information.
