The Polymerization and Copolymerization of Allyl Phenyl Ether and Vinyl Phenyl Ether

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1965
アリルフェニルエーテル(APE)およびビニルフェニルエーテル(VPE)の重合性を比較するために研究を行なった。両モノマーはともにラジカル単独重合性に乏しく,過酸化ベンゾイルを用いた場合に低収率でワックス状ポリマーを与えるのみであった。また,塩化ビニル(VC)との共重合においても仕込みモノマー混合物中のAPEおよびVPEの濃度が増大すると著しく共重合速度を低下した。得られた共重合体組成より求めた反応比およびこれらモノマーのQ,e値はつぎのごとくであった。r(APE)=0.30,r(VC)=2.52:Q(APE)=0.018,e(APE)=-0.24r(VPE)=0.43,r(VC)=1.93:Q(VPE)=0.024,e(VPE)=-0 ...
