Template copolymerization of acrylamide (AM) with acylic acid(AA) was carried out in the presence of polyallylammonium chloride (PAAC) as matrix in aqueous solutions．The various influences on the rate of polymerization were studied by dilatometer and electrical conductivity measurements．The obtained results indicated that the process of copolymerization under the effect of polyallylammonium salt was according to type I (zip) template mechanism．The maximum of reaction rate was appeared at equivalence mole ratio of template unit (T) to monomer AA. T／AA=1 indicated a high interaction between the monomer AA and the template in the solution．The reactivity ratios of r1 2.68 for AA and r2 0.44 for AM were also obtained. The considerable enhancement of r1 compared with that without the template indicated that the presence of PAAC significantly increases the probability of long sequences of AA unites in copolymers．The rate of polymerization was found to be proportional to the concentration of monomers and initiator with exponents of 1.1 and 0.83

respectively

which are larger than the ordinary values due to the effect of PAAC．
