G. Mannebach et al., ON THE ANIONIC-POLYMERIZATION OF DIALKYLAMINOISOPRENES, 4 - PART 3 - EXPERIMENTAL-OBSERVATION OF THE UNUSUAL POLYMERIZATION KINETICS, Macromolecular chemistry and physics, 199(5), 1998, pp. 909-912
The anionic polymerization of 5-(N,N-dialkylamino)isoprenes with sec-b
utyllithium was investigated in different solvents under various condi
tions. The homopolymerization can be described as a 2(nd) order reacti
on with respect to the monomer concentration, indicating that two mono
mer units are involved in the rate determining reaction. A mechanistic
proposal to explain this unusual behaviour is based on the structure
of amino-functional lithium organic compounds.
