Abs . . plastics piping systems for industrial applications - acrylonitrile - butadiene - styrene , unplasticized poly vinyl chloride and chlorinated poly vinyl chloride - specifications for components and the system - metric series 工业用塑料管道系统.丙烯腈-丁二烯-苯乙烯共聚物
Lts membrane properties and effect on cross - iinking biomoiecuiars were discussed . protein a was selected as a sensing membrane owing to the fact that it contains a active spot which can bind fc portion of antibodies . so the orientated immobilization of antibody was achieved 丁二烯-苯乙烯共聚物作为膜材料，研究了膜的性质和对生物大分子修饰的效果；另外，对具有专一性结合抗体fc功能区的蛋白a作为中间链接层进行了膜性质、定向修饰功能、重复性方面的研究。
Protein a and styrene - butadiene - styrene ( sbs ) were selected as sensing membrane to cross iink antibodies ; sbs , poiyvinyi chloride ( pvc ) and poiystyrene ( ps ) are polymers and have many advantages such as easiiy obtained , convenientiy forming membranes and easi1y modified by the introduction of other functional groups . pvc . ps and sbs were used as precoating materials for immobiiizing antibody in our experiment 选择了两种固定生物大分子的敏感膜：首先，从具有原料易得，成膜方法简单，可以进行表面改性等优点的聚氯乙烯、聚苯乙烯、聚苯乙烯-丁二烯-苯乙烯共聚物三种高分子中选择出成膜迅速、均匀、膜的稳定性好、响应迅速、而且易于控制涂层厚度等优点的聚苯乙烯
