研究了TPX、乙丙共聚物、中1,2-聚丁二烯和3,4-聚异戊二烯及其共混改性聚合物的均质膜的成膜规律和工艺方法,提出了“液面框架成膜法,成功地解决了强度低,、室温处于高弹态聚合物均质膜的制膜困难。用SEM.DSC.WAXD和POM分析了膜的形貌和形态结构、以压力法和体积法测定了膜的氧氮选择透过性,发现溶剂蒸发温度和后处理条件对膜的表面形貌,形态结构及气体透过性产生深刻影响;大分子共混改性TPX膜的结晶度降低;除等规聚丙烯和3,4-聚异戊二烯外、其余所研究的聚合物膜的P_(O_2)达10~(-9)(cm~3(STP)cm/cm~2.s.cmHg],α-(O_2)/N_2为2.8—5.0,改性TPX的气体透过性及透过稳定性较改性前有所改善。
The film forming rules and process methods of TPX, ethylene-propylene copolymer, 1,2-polybutadiene and 3,4-polyisoprene and their modified polymers were studied. "The liquid surface film-forming method has successfully solved the problem of low strength and difficult film formation at high elastic polymer homogenized film at room temperature.The morphology and morphological structure of the film were analyzed by SEM.DSC.WAXD and POM Pressure and volumetric methods were used to determine the oxygen and nitrogen permeability of the membrane. The results showed that the solvent evaporation temperature and the post-treatment conditions had a profound effect on the surface morphology, morphology and gas permeability of the membrane. (P_ (O_2)) of the polymer films except for isotactic polypropylene and 3,4-polyisoprene reached about 10-9 cm -3 (STP) cm / cm ~ 2.s.cmHg], and a - (O_2) / N_2 is 2.8-5.0. The gas permeability and the trans-stability of the modified TPX are improved compared with those before modification.
