Jr. Quintana et al., MICELLE FORMATION AND ANOMALOUS BEHAVIOR IN THE SYSTEM POLYSTYRENE-BLOCK-POLY(ETHYLENE PROPENE) POLY(ISOBUTENE) 5-METHYL-2-HEXANONE, Die Makromolekulare Chemie, 194(9), 1993, pp. 2497-2505
Solubilization of poly(isobutene)a) by micelles of polystyrene-block-p
oly(ethylene/propene) block copolymer with a copoly(ethylene/propene)
core was investigated. The weight of poly(isobutene) solubilized was f
ound to be proportional to the concentration of block copolymer in the
solution. No influence of the presence of poly(isobutene) on the crit
ical micelle temperatures has been found. However, the addition of pol
y(isobutene) to the micellar solution seems to favour the anomalous be
haviour found in micellar solutions of the block copolymers used in th
is study.
