MSED Virtual Seminar

October 14, 2020 @ 1:30 pm - 3:30 pm

The Macromolecular Science and Engineering Division (MSED) of the Chemical Institute of Canada is dedicated to promoting the interests of the Canadian polymer science and engineering communities and recognizes excellence in polymer research at all levels with annual faculty, graduate, and undergraduate awards. Given the current restrictions that the COVID-19 pandemic has posed in organizing in-person conferences, and witnessing tremendous success that has been achieved by various online seminar series, MSED is initiating a series of virtual seminars (MSED-VS) to keep up the spirit of the researchers in this community, facilitate showcasing recent results, and enable researchers to connect and exchange ideas from the comfort of their home and/or office.

MSED-VS will host talks in all areas of polymer science and engineering, ranging from polymer synthesis and characterization to their applications in various exciting areas of science and technology. For the Fall season, talks will be held on a monthly basis on Wednesdays at 1:30 pm. Participation is free of charge for everyone!

Speaker: Prof. Krzysztof (Kris) Matyjaszewski, J. C. Warner University Professor of Natural Sciences and Director, Center for Macromolecular Engineering, Carnegie Mellon University, USA

Abstract: Copper-based ATRP (atom transfer radical polymerization) catalytic systems with polydentate nitrogen ligands are among most efficient controlled/living radical polymerization systems. The control in ATRP is defined by the dynamic equilibration between active propagating radicals and dormant alkyl halide species. Recently, by applying new initiating/catalytic systems, Cu level in ATRP was reduced to a few ppm. ATRP of acrylates, methacrylates, styrenes, acrylamides, acrylonitrile and other vinyl monomers was controlled by various external stimuli, including electrical current, light, mechanical forces and ultrasound to regenerate very low concentrations of activators.  ATRP was employed for synthesis of multifunctional polymers with precisely controlled complex molecular architecture with designed shape, composition and functionality. Block, graft, star, hyperbranched, gradient and periodic copolymers, molecular brushes and various hybrid materials and bioconjugates were prepared with high precision. These hybrids provide access to new materials for application related to biomedicine, environment, energy and catalysis.
