Blending procedures

The blends were prepared with two take-up speeds to achieve morphologies with different LCP fiber dimensions. The lower speed (L), leading to a draw ratio of 1 1, represents the normal blending procedure, which was what we used in our previous work [44]. The higher speed (H) resulting in a draw ratio of 6 1 was applied to form long highly oriented LCP fibers. The draw ratio for each strand was determined as the ratio between the die and strand cross-sections (Sq/Ss). 

Since feed streams are not added after the start of a batch reaction one need only be concerned with proper initial addition and blending procedures. Streams flowing into a CSTR, however, are being introduced into a polymer latex. If added improperly, these streams can fail to be mixed completely and they can cause flocculation. Streams should be introduced where they are mixed rapidly and the ionic concentration should be as low as possible. Introduction of such streams as initiator solutions at high concentrations or in the wrong location can cause local flocculation and/or non-uniform reaction. 

VMA s, these methods will not necessarily produce a mix with the lowest VMA possible with the aggregates available. The particle shape and surface, boundary effects from the container, compact-ive effort and the ratio of the "sizes" of the aggregates must all play a part in the blending procedure.
