摘要： Novel, expandable polymeric blends comprising at least one vinylaromatic monomer-acylonitrile resinous material, an effective amount of at least one blowing agent, and from about 0.2 to about 1.0 percent by weight, based on the weight of resinous material, of an expansion aid consisting essentially of triethylene glycol. The triethylene glycol expansion aid unexpectedly reduces the amount of expansion agent required to expand the composition, particularly to low density products, without adversely affecting the final properties of the foamed product.

摘要： An inventive solid state drawing die has shaping walls that define a shaping channel and that, in the course of solid state drawing, direct polymer composition along a drawing path. Each cross section of the drawing path (and, hence, polymer composition in the drawing path) is non-circular, substantially proportional to one another, contains a centroid that lies on a substantially straight line parallel to the drawing direction and all cross sectional dimensions are 1.5 millimeters or more.
