The grafting reaction with methyl methacrylate is generally completed in the early stage of reaction both with DBHA and DBHY.
The reaction kinetics with DBHY is a little slow compared to that with DBHA. Based on the data as a function of time, the reaction rates.
For the reaction with DBHA, [K.sub.g]/[(1 + f)[K.sub.t.sup.1/2]] is 0.01 [(liter/mole-sec).sup.1/2].
On the other hand, according to Dbha 9.28, tad aparinitasudraputrabhiprayam.
The degree of maleic anhydride grafting with DBHY is slightly higher than that with DBHA. The degree of grafting with BPO is much lower than those with the two other peroxides.
The rate of grafting with DBHY is relatively slow compared to that of DBHA. The degree of grafting with DBHY achieved 45% of the maximum reaction yield in 1 minute 30 seconds, 80% in 2 minutes, and almost 90% in 2 minutes 30 seconds.
During reactive extrusion with 1% initial maleic anhydride and 0.2 % DBHA, the mean residence time was determined to be 187 seconds.
Addition of DBHA causes significant drops of the melt viscosity of polypropylene compared to the original polymer.
The rate of grafting with DBHA is slightly faster than that with DBHY.
The incorporated styrene grafting yield decreases in order of DBHY, DBHA, and BPO.
The value of [K.sub.p]/[[K.sub.t].sup.1/2]] for styrene grafting plus homoplymerization reaction with DBHA is 0.16 [(liter/mole.sec).sup.1/2] with the 0.6087 [s.sup.-1] of [k.sub.d] value at 230[degrees]C.
