Development of Fibers Containing a Reaction Product of Chloromethylated Styrene Polymer and Diethylenetriamine.

摘要

Fibers with an anion exchange capacity as high as 2.7meq/g were obtained by preparing ion exchange resins in situ within two phase fiber systems. Initially,blends of polypropylene with acrylonitrile-butadiene (NBR) and a styrene containing polymer (ABS) were melt spun into two phase fibers,then drawn and crosslinked with peroxide or heat. Following this,the fibers were chloromethylated with chloromethyl methyl ether and aminated with diethylenetriamine. Unfortunately,the resulting fibers were very weak. Attempts were made to scale up the process to obtain larger sample sizes adequate for more extensive testing. (Modified author abstract)
