Mono-alkene and alkadiene proportions at different Curie-point temperatures Temperature, [degrees]C Mono-alkene, area% Alkadiene, area% 386 2.37 -- 423 24.85 -- 485 21.44 -- 590 31.47 1.51 650 27.90 3.81 764 25.96 6.50 Table 4.
Addition of a "randomizer," such as THF or TMEDA, would balance the ratio of styrene and alkadiene. As a result, the number of long polystyrene block in SIBR-THF or SIBR-TMEDA was much fewer than that in SIBR-1.
Therefore, when monomer mixture was polymerized in the solution, styrene could not be consumed unless both the alkadienes were almost polymerized to build a chain without styrene units.
