Taw qhia rau Organophosphorus Polymers

Nyob rau xyoo 1930, JA Alvin ntawm DuPont hauv Tebchaws Meskas tau pib tshawb fawb txog organophosphorus polymers, siv bisphenol A los ua haujlwm nrog phosphorus trichloride kom tau txais cov khoom lag luam uas tsis muaj dej thiab infusible. Txij li thaum xyoo 1940, lub hom phiaj ntawm kev kawm organophosphorus polymers yog tsuas yog nrhiav cov ntaub ntawv polymer nrog cov khoom tshwj xeeb, xws li nplaim hluav taws kub, kub tsis kam, hnyav tsis kam, tsis tshua muaj kub thiab UV tsis kam. Tam sim no nws tau txuas ntxiv mus ua kom paub cov organic pawg ntawm cov pob txha ntawm inorganic phosphorus polymers. Piv txwv li, lub cyclized trimer ntawm dichlorophosphine (NPCl2) 3 tuaj yeem ua polymerized rau hauv cov kab hluav taws xob polymer ntawm qhov kub thiab txias, thiab tom qab ntawd cov tshuaj chlorine atom hloov nrog sodium alkoxide los ua polyalkoxyphosphine polymer: Thaum R yog CF3CH2, C3F7CH2 Lub melting kub ntawm lub polymer yog siab li 240 degree los yog ntau tshaj, thiab nws yuav siv tau raws li roj-cov kav dej thiab gaskets, nrog rau cov nplaim taws- tiv taus thiab poob siab{12}} cov ntaub ntawv pov thawj ntawm -60 rau 200 degree.
