Precision, Tunable Deuterated Polyethylene via Polyhomologation



Wesley Farrell, Sara Orski, Anthony Kotula, Kathryn Beers, Daniel Baugh


Polyhomologation (also known as "C1 polymerization") of a deuterated ylide has been performed, which yields linear polyethylene of high deuterium content. Copolymerization with the protonated analog allows for the preparation of sta-tistical copolymers, in which linear polyethylene with a uniform and tunable amount of deuterium is obtained. The amount of deuterium present, as well as its uniform distribution, is supported by vibrational spectroscopy, size-exclusion chromatography with infrared detection, and 2H nuclear magnetic resonance spectroscopy. This technique was extended to prepare a precision triblock copolymer in which the chain-ends are selectively deuterated. All polymers re-ported are of narrow dispersity, and will find use in myriad measurements sensitive to deuterium labeling, most notably small-angle neutron scattering.
