 oxygen in radical polymerization
I'm looking for references in the area of oxygen consumption (?)
during radical emulsion polymerization of styrene-acrylonitrile.
In an open reactor (in equilibrium with atmospheric oxygen),
how much oxygen is typically consumed by the reaction ? Has
anyone ever done any mass-balance calculations or measurements
in this area ?

I am interested in making fluorescence measurements on styrene
monomer in such a system, and need to understand the oxygen
content variations.

Maybe you should try looking up the work of Prof. Soutar at the University
of Lancaster in the UK. I believe he has done a great deal of work on
using fluorescence as an analytical probe in polymer chemistry.

Good Luck

 oxygen in radical polymerization
Hi

I am trying to study certain aspects of molecular weight of polymers and their
effect on crystallization. I am also trying to understand the effect of foreign
inclusions on the crystallizability in crystalline polymer systems. I would appreciate
any related information pertinent to these areas and also about references available
in the literature.

Thanks in advance

Can't give you a lot of information. Most of my experience is in solvent
solutions, and keeping them solublized.  The more pure (lesser amounts of
dimer, trimer, by-products) the more readily they fall out of solution
over time, and generally have to be re-heated to maintain solubility.
