    Abstract: This invention provides a technique for extremely rapid dissolution, or dispersion on essentially the molecular level, of certain polymeric materials in compatible liquid vehicles. The polymeric materials are comminuted at cryogenic temperatures and are then introduced into a liquid vehicle preferably while still at or near cryogenic temperature. At low concentrations, the resulting blend or system displays reduced friction to flow while high concentrations may be used to immobilize the liquid vehicle and/or reduce its vapor pressure.

    Abstract translation: 本发明提供了在兼容液体载体中的某些聚合物材料上极快地溶解或分散在基本上分子水平上的技术。 聚合物材料在低温下粉碎,然后优选在低温或接近低温时引入液体载体。 在低浓度下,所得到的混合物或体系显示减少的流动摩擦力,而高浓度可用于固定液体载体和/或降低其蒸汽压力。
