Abstract

The advent of small angle neutron scattering (SANS) allows the direct measurement of parameters in the realistic environment of the polymer melt. An added advantage is the capacity to carry out measurements over a much wider temperature range than is usually feasible via the theta-solvent approach. Generally, through, SANS measurements have been conducted at either a single temperature or over only a narrow range of temperatures. One exception is the work of Ballard et al on isotactic polypropylene (i-PP) which covered the temperature range of 23 to 220°C; thus embracing both the crystalline and amorphous regimes.
