Characteristics of novel transparent poly(methyl methacrylate)/silica nanoparticle hybrid film prepared based on entanglement-agglomeration transition mechanism

Autor: Takashi Sawaguchi, Toru Hoshi, Yoshio Muroga, Rui Zhu, Tsuyoshi Tadano, Toshiki Hagiwara, Sasaki Daisuke

Publikováno v: Polymer Journal. 47:311-319

The critical molecular weight (Mc), at which the entanglement effect of the PMMA chain occurs is ~3 × 104. When the PMMA molecular weight in the hybrid suspension and film is such that Mc < Mw, such formation of molecular chain entanglements acts as

Thermal degradation of transparent poly(methyl methacrylate)/silica nanoparticle hybrid films

Autor: Shota Suzuki, Takashi Sawaguchi, Rui Zhu, Sasaki Daisuke, Tsuyoshi Tadano, Toshiki Hagiwara, Toru Hoshi

Publikováno v: Polymer Degradation and Stability. 109:7-12

Using thermogravimetric (TG/DTG) analysis, we evaluated the thermal degradation characteristics of transparent poly(methyl methacrylate) (PMMA)/silica nanoparticle hybrid films obtained by well dispersing surface-unmodified silica (SiO 2 ) nanopartic

Catenane gel: synthesis of high molecular weight poly[2]catenanes by Sonogashira coupling polymerization

Autor: Yuki Watanabe, Yasuhiro Murano, Takashi Sawaguchi, Toshiki Hagiwara, Toru Hoshi

Publikováno v: Tetrahedron Letters. 53:2805-2808

A first catenane polymer gel was obtained by Sonogashira coupling reaction of diiodo[2]catenane and 4,4′-diethynylbiphenyl. Because of the linearity and rigidity of the ethynylene group formed in the coupling reaction, the formation of undesired cy

Microstructure and mechanical properties of a polyethylene/polydimethylsiloxane composite prepared using supercritical carbon dioxide

Autor: Shoichiro Yano, Yoshio Muroga, Toshiki Hagiwara, Toru Hoshi, Takashi Sawaguchi, Rui Zhu

Publikováno v: Journal of Applied Polymer Science. 127:3388-3394

A polymer composite of polyethylene (PE) and polydimethylsiloxane (PDMS) was prepared using supercritical carbon dioxide despite the two polymers usually being immiscible and possessing a phase-separated morphology. This article reports in detail the

Synthesis of poly[2]catenane having rigid linkage by 1,3-dipolar cycloaddition of diazido[2]catenane with 4,4′-diethynylbiphenyl

Autor: Shoichiro Yano, Tomohiro Suzuki, Toshiki Hagiwara, Manabu Yamazaki, Takashi Sawaguchi

Publikováno v: Polymer. 52:5426-5430

A novel poly[2]catenane having rigid triazole rings between [2]catenane moieties was synthesized by the 1,3-dipolar cycloaddition of diazido[2]catenane with 4,4′-diethynylbiphenyl. The reaction proceeded effectively under mild conditions and gave a

Publikováno v: Polymer Journal. 42:562-566

Blends of polyethylene (PE) and polydimethylsiloxane (PDMS) are usually immiscible and have phase-separated morphology. In this study, the polymer composite comprising PE and PDMS with a hydrophobic surface was developed. This composite was obtained
