In this study,the independent development of the process for the manufacture of poly(styrene-co-N-phenyl-maleimide)(SNPMI),a kind of heat-resistant resin,and the optimal design of the complex reactive extrusion process was focused on.

Meanwhile, high-temperature strongly acidic catalyst resin was firstly used as methanol dehydration catalyst, and the effect of factors, such as temperature, pressure and space velocity were discussed, then the optimal reactio.
