Description
vh、vdより、樹脂のSP値δは、SUH,CLARKE[J. Polym. Sci. A-1 , Vol.5 ,1671-1681 (1967)]により示された式を用いて、以下のようにして、求めることができる。
δ=〔(Vmh)(1/2) ・δmh+(Vmd)(1/2) ・δmd 〕/〔(Vmh)(1/2)+(Vmd)(1/2) 〕
ここで、
Vmh=(Vh・Vt)/(φh・Vt+φ ht ・Vh)、Vmd=(Vd・Vt)/(φd・Vt+φ dt ・Vd)
δmh=φh・δh+φ ht ・δt、δmd=φd・δd+φ dt ・δt
φh,φ ht ;滴定溶剤にヘキサンを使用したときの、濁点における、ヘキサン,THFの体積分率
φ d ,φ dt ;滴定溶剤に脱イオン水を使用したときの、濁点における、脱イオン水,THFの体積分率
〔φh=vh/(vh+10)、φ ht =10/(v h +10)、φd=v d /(vd+10)、φ dt =10/(v d +10)〕〔但し、10はTHFの使用容量(10ml)である。〕
δh,δd,δt;ヘキサン,脱イオン水,THFのSP値
Vh,Vd,Vt;ヘキサン,脱イオン水,THFの分子容(ml/mol)
From v h and v d , the SP value δ of the resin can be calculated by the following formula using SUH, CLARKE [J. Polym. Sci. A-1, Vol. 5, 1671-1681 (1967)]. In this way, it can be determined.
δ = [ ( Vmh ) (1/2) · δmh + ( Vmd ) (1/2) · δmd ] / [ ( Vmh ) (1/2) + ( Vmd ) (1/2) ]
here,
V mh = (V h · V t) / (φ h · V t + φ ht · V h), V md = (V d · V t) / (φ d · V t + φ dt · V d)
δ mh = φ h · δ h + φ ht · δ t, δ md = φ d · δ d + φ dt · δ t
φ h , φ ht ; volume fraction of hexane and THF at the turbid point when hexane is used as the titration solvent
φ d , φ dt ; volume fraction of deionized water and THF at the turbid point when deionized water is used as the titration solvent
[Φ h = v h / (v h +10), φ ht = 10 / (v h +10), φ d = v d / (v d +10), φ dt = 10 / (v d +10) ] [However, Reference numeral 10 denotes the used volume of THF (10 ml). ]
δ h , δ d , δ t ; Hexane, deionized water, THF SP value V h , V d , V t ; Hexane, deionized water, THF molecular volume (ml / mol)
