Polyvinylpyrrolidone K90
Product Description:
Cov khoom no yog tau los ntawm polymerizing pyrrolidone thiab ethylene los tsim vinyl pyrrolidone monomer nyob rau hauv siab thiab polymerizing nws nyob rau hauv qhov kev txiav txim ntawm ib tug catalyst. Lub homopolymer ntawm 1-vinyl-2-pyrrolidone muaj qhov nruab nrab molecular hnyav ntawm 3.8X104 thiab cov mis molecular yog (C6H9NO)n, qhov twg n sawv cev rau tus lej nruab nrab ntawm 1-vinyl-2-pyrrolidone chains.
