Abstract
In the present study the copolymerizatioin was carried out between Isobutyl
acrylat (IBA) and butyl acrylate with different molar ratio. ( 0.2 m1/0.8 m2 -----
to 0.8 m1/0.2 m2 ) Where m1 represent (IBA) and m2 (BA) .
The Polymarization was carried out by free radical using (AIBN) as inititor at
70ºC. The reactivity ratios r1 and r2 of monomers participated in the reaction
which leads to (IBA-co-BA) system . where Calculated using three method
mayo- lewis as well as Finemane – Ross and Kelen-Tudos were used method to
measure the percentage of reactivity ratios were adopted .The percentage of
measure reactivity was found to be r1= 0.084 and r2 = 2.022
This means that the reactivity of butyle acrylat (BA) m2 is greater than
reactivity of (IBA) m1 and the copolymer is Random because the multiplication
product of r1 with r2 equal to 00169 which is less than one. r1 r2 than one.
