Characteristics of polymers used in this study.

Polymer code	M w/104	M w/M n [a]
Mal/C12-1	0.86[b]	1.5
Mal/C12-2	3.4 [c]	1.8
Mal/C12-3	70 [d]	1.7

^[a] Determined by size exclusion chromatography for unhydrolyzed samples in tetrahydrofuran. Molecular weights were calibrated with polystyrene standards.

^[b] Calculated from the M _n determined by vapor pressure osmometry and the M _w/M _n determined by size exclusion chromatography for an esterified sample.

^[c] Determined by sedimentation equilibrium in methanol containing 0.1 M LiClO₄.

^[d]Determined by static light scattering in methanol containing 0.1 M LiClO₄.
