Publikováno v: Polymer. 50:1300-1303

The second virial coefficients A 2 of ring polystyrenes with high purity in cyclohexane were measured by light scattering in the temperature range 27.0–34.5 °C. The purity of four samples with M w of 16k, 42k, 110k and 570k was determined to be al

Autor: Y. Ohta, Yushu Matsushita, Daisuke Kawaguchi, Yuuki Kushida, Atsushi Takano

Publikováno v: Macromolecules. 41:3957-3961

A catenated copolymer consisting of cyclic polystyrene (PS) with short poly(2-isopropenylnaphthalene) (PIPN) segments and cyclic polyisoprene (PI) were prepared by living anionic polymerization. The molecular weight of catenated copolymer is 37 kDa.

SEC–MALS characterization of cyclization reaction products: Formation of knotted ring polymer

Autor: Atsushi Takano, Yushu Matsushita, Yuuki Kushida, Y. Ohta

Publikováno v: Polymer. 50:1297-1299

Cyclization reaction products by the end-to-end ring closure of telechelic polystyrenes (PSs) with molecular weight of 47 k and 380 k in THF (good solvent) and also in cyclohexane (poor solvent) were characterized by SEC connected with multi-angle li

Autor: Kenichi Hayashida, Yuuki Kushida, Yushu Matsushita, Keisuke Masuoka, Atsushi Takano, Donghyun Cho, Kayoko Aoki, Daisuke Kawaguchi

Publikováno v: Macromolecules. 40:679-681

Cyclization reaction product synthesized by the end-to-end ring closure reaction of a telechelic polystyrene with molecular weight of 38K in extremely dilute conditions was carefully characterized by using two kinds of HPLC techniques, that is, liqui
