A Coarse-Grained Model for Polyethylene Oxide and Polyethylene Glycol: Conformation and Hydrodynamics [PDF]
The Journal of Physical Chemistry B, 2009 A coarse-grained (CG) model for polyethylene oxide (PEO) and polyethylene glycol (PEG) developed within the framework of the MARTINI CG force field (FF) using the distributions of bonds, angles, and dihedrals from the CHARMM all-atom FF is presented. Densities of neat low molecular weight PEO agree with experiment, and the radius of gyration R(g) = 19 ...

Ultraviolet Oxidation of Polyethylene
Kobunshi Kagaku, 1965 分岐度および二重結合量の異なる高圧法, 中圧法, 低圧法ポリエチレンフィルムに254, 316, 336, 354, 380mμ にそれぞれ主波長をもつ光源を使用して紫外照射を行ない, 紫外線酸化における波長依存性について赤外線吸収スペクトル, 密度および結晶化度, Melt flow rate, 不溶解分の測定を行なって検討した。その結果, 低エネルギー紫外線により結合エネルギーの小さい二重結合に対するβ位のC-H結合が攻撃され, 高エネルギー紫外線により分岐部のtertiary C-H結合も攻撃されることを確認した。また, 高エネルギー紫外線により高圧法ポリエチレンは橋かけ反応が, 中圧法, 低圧法ポリエチレンは切断反応が優先することを認めた。
