(JA) ビニルアルコール系重合体及びその用途
Abstract: front page image
(EN) A vinyl alcohol polymer having an ethylenic double bond and a saponification degree of 70% by mole or more, which is characterized by being soluble in water and is also characterized in that: the molar ratio of the ethylenic double bond to the total of a vinyl alcohol unit and a vinyl acetate unit is from 0.05/100 to 2/100; and the limiting viscosity [η] and the weight average molecular weight Mw of a vinyl ester polymer that is obtained by esterifying the vinyl alcohol polymer satisfy the following formulae (1) and (2). 4.7 ≤ logMw ≤ 6.3 (1) 0.60 < (log[η] + 3.75)/logMw < 0.69 (2)
(FR) L’invention concerne un polymère d'alcool vinylique ayant une double liaison éthylénique et un degré de saponification de 70 % par mole ou plus, qui est caractérisé en ce qu'il est soluble dans l'eau et est également caractérisé en ce que : le rapport molaire de la double liaison éthylénique sur le total d'un motif alcool vinylique et d'un motif acétate de vinyle est de 0,05/100 à 2/100 ; la viscosité limite [η] et le poids moléculaire moyen en poids Mw d'un polymère d'ester vinylique qui est obtenu en estérifiant le polymère d'alcool vinylique satisfont les formules (1) et (2) suivantes. 4,7 ≤ logMw ≤ 6,3 (1) 0,60 < (log [η] + 3,75)/logMw < 0,69 (2)
(JA)  エチレン性二重結合を有し、けん化度が70モル%以上であるビニルアルコール系重合体であって;前記ビニルアルコール系重合体が水溶性であり、ビニルアルコール単位と酢酸ビニル単位の合計に対する前記エチレン性二重結合のモル比が0.05/100~2/100であり、かつ前記ビニルアルコール系重合体をエステル化して得られるビニルエステル系重合体の極限粘度[η]と重量平均分子量Mwが下記式(1)及び(2)を満たすことを特徴とするビニルアルコール系重合体。 4.7≦logMw≦6.3 (1) 0.60<(log[η]+3.75)/logMw<0.69 (2)
