Abstract

The purified methyl acrylate and acrylonitrile have been polymerized at there different temperatures by using benzoyl peroxide as initiator. The limiting viscosity numbers of ali the polymer samples were measured. As ve have expexted, the limi¬ting viscosity numbers or the number average molecular weights of the polymers decreased with increasing temperature.
A relationship between the limiting viscosity numbers and the temperatures has been obtained as follow,
1
for PMA : log [»?] = — 0.56 + 5 x 102
T
1
for PAN : log [»;] = — 0.40 -|- 5 x 102 ——
T
