PVP K90

Product Description:

Cov khoom no yog tau los ntawm polymerizing pyrrolidone thiab ethylene los tsim vinyl pyrrolidone monomer nyob rau hauv siab thiab nyob rau hauv qhov kev txiav txim ntawm ib tug catalyst. Lub 1-vinyl-2-pyrrolidone homopolymer muaj qhov nruab nrab molecular hnyav ntawm 3.8X104 thiab cov mis mos molecular yog (C6H9NO)n, qhov twg n nruab nrab tus naj npawb ntawm 1-vinyl-2- pyrrolidone chain ntu.

Lub cev muaj zog:

Solubility thiab kev daws cov yam ntxwv

Cov tshuaj aqueous ntawm PVPK90 tsis yog-thixotropic feem ntau thiab muaj lub sijhawm so luv luv. Thaum cov concentration loj, nws yuav muaj qee yam qauv viscosity: thaum lub zog shear nce, lub viscosity yuav txo. Kev tswj hwm qhov concentration ntawm PVPK90 yuav coj ntau yam kev thov sib txawv rau PVPK90.

Qhov dav ntawm qhov hnyav molecular faib thiab nws qhov cuam tshuam:

Zoo li txhua yam khoom siv dawb radical polymerization, PVP muaj ib yam Schulg-Ftory molecular hnyav tis. Raws li qhov siab molecular hnyav PVPK90 hauv PVP series, nws qhov hnyav molecular faib nkhaus feem ntau yog dav, vim tias qhov hnyav molecular ntau dua, uas feem ntau dhau los ua ntau ceg. Qhov siab dua qib ntawm grafting, qhov loj dua qhov hnyav molecular thiab qhov dav ntawm kev faib khoom. Lub cev hnyav molecular faib ntawm PVPK90 tuaj yeem tswj tau zoo txhawm rau txhawm rau siv nws qhov kev ua tau zoo hauv daim ntawv thov, txwv tsis pub nws qhov kev ua tau zoo yuav raug txwv thiab qhov kev cia siab siv yuav tsis ua tiav.
