| heal.abstract | Three 6-miktoarm star (6 mu-star) copolymers [PS(P2MP)(5)] of styrene (S) and 2-methyl-1,3-pentadiene (2MP) were synthesized by anionic polymerization and controlled chlorosilane chemistry, using high vacuum techniques. In all cases [M-w = 103 kg/mol, [S] = 44% (v/v); M-w = 91.1 kg/mol, [S] = 53% (v/v); M-w = 224 kg/mol, [S] = 92% (v/v)] the P2MP exhibited high 1,4-microstructure (similar to 99%). Molecular characterization (size-exclusion chromatography, membrane osmometry, low-angle laser light scattering, and NMR) revealed high molecular weight/composition homogeneity, and structural analysis (differential scanning calorimetry, transmission electron microscopy, and small-angle X-ray scattering) showed highly ordered patterns. The deviations from predictions based on Milner's morphological model are much more pronounced than that of PS(P2MP)(2) and PS(P2MP)(3) miktoarm stars, which we attribute to greater crowding of the arms for these highly branched molecules. | en |
