High molecular weight polymers with uniform dispersity are produced. Kinetic data from NMR studies and MALDI-TOF MS data of the polymers provide some mechanistic insight.

However, expansion of starch significantly increases the surface area to between 100-180 m2/g, creating a low d., mesoporous material that can be potentially exploited in chromatog. In this study, the phys. properties, hydrothermal stability and chromatog. characteristics of expanded starch have been investigated and compared to native starch and com. available Kieselgel 60 silica gel. Subsequently, a no. of families of compds. were investigated in order to assess the versatility of expanded starch in column or flash chromatog. The materials provided comparable sepns. to that of silica with the added advantage of requiring less stationary phase (by mass), being non-toxic and biodegradable. In addn., the lower polarity exhibited by expanded starch compared to silica could potentially represent an attractive asset for this novel material in the sepn. of highly polar compds.
