Abstract: Using α,α'-azobisisobutyronitrile (AIBN) as an initiator, the telomerization of Methylmethacrylate (MMA) with Carbon tetrachloride (CC1_4) was carried out in variable conditions, in order to prepare the low molecular weight polymers or oligomers. And then the effect of time of reaction, temperature of reaction, molar ratio of MMA to CC1_4 and an initiator concentration on the rate of reaction and molecular weight of telomer was investigated. The results show that, 1. in the range of temperature from 50 to 100℃, the molecular weight of telomers diminishes as temperature and time increase, and observed activation energy was ca. 9Kcal/mole, 2. in the variable molar ratio of [CMMA]/[CC1_4](=0.2~2.0), the rate of reaction shows maximum as molar ratio was 1.0, and the constant of chain transfer was 3.49×lO^<-2>, 3. the initial rate of reaction was in proportion to square root of initiator concentration as well as general radical polymerization.
