Since, the values of kp,h and kp,g are the same (Zkp) in the solution graft copolymerization [5], it is interesting to examine
if the propagation rate coefficient (kp) of AA obtained from the solution polymerization at low temperature are fitting for kp,g in the melt.
The data, kp of AA in aqueous solution at concentration of 40 wt% and temperature between 2.6 and 28.5 8C [16] are extrapolated to 130–170 8C, and compared with kp,g in Table 3
