A transportable polymer-fluid composition and process for making the same is described. The composition comprises
(I) a dissolved fluid which at normal temperature and pressure at standard conditions of 0°C. and one atmosphere (STP) is a gas; and
(II) a thermoplastic or thermosettable polymer having
(a) a plurality of moieties with the intermolecular disruption characteristics of mono, di or tri substituted fluorine on carbon and mono, di or tri substituted methyl on carbon or silicon, in which said carbon and silicon are a part of, or are directly or indirectly covalently attached to, the skeleton of the polymer's main structure, and are each no more than about 12 covalently bonded atoms from the covalent linkage to an atom in the main structure of the polymer, and
(b) the properties of
(i) enhanced expansivity,
(ii) reduced cohesive energy density or
(iii) both (i) and (ii),
thereby allowing more fluid (I) to be dissolved therein.
描述了一种可运输的聚合物流体组合物及其制造工艺。该组合物包括
(I) 一种溶解流体,该流体在常温常压下,在 0°C 和一个大气压 (STP) 的标准条件下为气体;以及
(II) 热塑性或热固性聚合物,具有以下特性
(a) 具有碳上单取代、二取代或三取代氟和碳或硅上单取代、二取代或三取代 甲基的分子间断裂特性的多个分子,其中所述碳和硅是聚合物主结构骨架 的一部分,或直接或间接共价连接到聚合物主结构骨架上,且从共价连接 到聚合物主结构中的一个原子,每个原子不超过约 12 个共价键,以及
(b) 具有以下特性
(i) 延展性增强
(ii) 降低内聚能密度,或
(iii) 同时具有(i)和(ii)两种特性、
从而使更多流体(I)溶解其中。
