Document Summary
Kinetics regardless of length of chain on which a is, same kinetics. 2= p2 (1 p)2: open system (remove h2o) P [ a ]0[ h 2o] (1 p)2[ a ]0. =kc [ a ][b ] rate law: c subscript stands for catalyst (common in industry to use catalyst) assume [a]0 = [b]0 [a] = [b] can solve diff eq now. [ a]2 =kc dt need initial condition at t = 0, [a] = [a]0. N n reciprocal of degree of polymerization since initial [a]0 = # monomers we started with. [a] = # polymers we have at the moment. Hard to get large molecular weight, m b/c any monomer can react with anything, so need to have to react very long time to get large p. Chain-growth polymerization if have chain with active site at an end, can react with monomer to add that monomer to the chain.
