styrene and methylmethacrylate copolymerization
The polymer when monomer more than two kind is existed to polymer because monomer more than two kind does polymerization at the same time . This polymerization is known as copolymerizations.
(1) Reaction and of copper polymerization form air conjunction
M1ㆍ + M1 M1 (1) M1ㆍ + M2 M2ㆍ (2)
M2ㆍ + M1 M1ㆍ (3) M2ㆍ + M2 M2ㆍ (4)
= k11[M1ㆍ][M1] + k21[M2ㆍ][M1] (5)
= k12[M1ㆍ][M2] + k22[M2ㆍ][M2] (6)
[M1ㆍ] = (7)
r1 = (8) r2 = (9)
d[M1]/d[M2]: Speed rain that two monomers are consumed. Finally, equal of monomer M1 of interpolymer and M2`s mol furtherance.
[M1]/[M2]: ratio of mol furtherance of monomer M1 and M2 in copolymerization.
(2) Decision of monomer reaction ratio
Fineman-Ross way : By way to save monomer reaction ratio r1 and r2
