Study on the Selective Separation by Poly- (fumarate) Thin Films

块状物质的富集同源物和二进制随机偶联如， di（isopropy 1）， di（tert-buty 1），di（cyclohexy 1），六氟异异opy 1，和bis（beta，beta-dimethy 1 phenety 1） [abb.，DiPF， DtBF， DcHF， F_6iP和BMPEF， resp。对[O_2/N_2/]-分离或[水/酒精]-分离材料进行了研究，在从DiPF、DtBF和DcHF的两个单体中制备了二进制随机拷贝，其中DtBF的拷贝含有DtBF含量的80mo1%最高气体渗透常数[P_<02>和P_<N2>]和分离因子， alpha。这一点值得注意的是，超过10^&lt;-8&gt; cm 3（STP）cm/cm^2·s·cmHg和超过4.0的Alpha可以被这样简单的聚合化作为外国单位的随机引入到基于DtBF的聚合物降解的晶体管中，也可以考虑[水/酒精]--通过隔离隔离方法不是成功的，对薄膜的大量消耗<02>，similar examination by“evapomeation”method revealed that PDiPF films are quite useful for concentrating alcohol especially when the concentration of alcohol is about 10%。PF_6iP或PBMPEF，希望有更多的高级蒸发材料，但不适合拍摄其硬度。进一步的研究以利用LB-电影过程将继续下去。

Fumarate homo- and binary random copolymers of bulky substituents such as, di(isopropy1), di(tert-buty1), di(cyclohexy1), hexafluoroisopropy1 isopropy1, and bis(beta, beta-dimethy1phenety1) [abb., DiPF, DtBF, DcHF, F_6iP and BMPEF, resp.] were synthesized and thier thin film properties as for [O_2/N_2/]-separation or [water/alcohol]-separation material were studied.Among the binary random copolymers prepared from the either two monomers of DiPF, DtBF and DcHF, DtBF-based copolymers with DtBF content of 80mo1% showed highest gas-permeation constants [P_<02> and P_<N2>] and separation factor, alpha. It is noteworthy that P_<02> of more than 10^<-8> cm^3(STP)cm/cm^2・s・cmHg and alpha of more than 4.0 can be attained by such simple copolymerization as the random introduction of the foreign units to the DtBF-based polymer decreased the crystallinity.Although the attempts to [water/alcohol]-separation by pervaporation method were not successful due to the swelling of films, similar examination by "evapomeation" method revealed that PDiPF films are quite useful for concentrating alcohol especially when the concentration of alcohol is about 10%. PF_6iP or PBMPEF, hopefully more advanced evapomeation material, were not suitable for filming due to their stiffness. Further study to utilize LB-filming process will be continued.
