Synthesis and properties of methacrylate-based ionic networked polymers containing ionic liquids: comparison of ionic and nonionic networked polymers

04-Jun-2010 | Kozo Matsumoto, Bandana Talukdar, Takeshi Endo, Polymer Bulletin, 2010

Ionic networked polymers containing ionic liquids were synthesized by radical copolymerization of 1-(2-methacryloyl)ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (Met-IL) and difunctional or trifunctional methacrylate cross-linkers, ethylene glycol dimethacrylate (EGDMA), or ...

Electron‐beam irradiation of blends of polypropylene with recycled acrylonitrile‐butadiene rubber

01-Jun-2010 | Ismail, H.; Galpaya, D.; Ahmad, Z., Journal of Vinyl and Additive Technology, 2010

One‐mm thick sheets were prepared from blends of polypropylene and recycled acrylonitrile‐butadiene rubber (rNBR) with different blend ratios. Trimethylolpropane triacrylate (TMPTA) was used as a co‐agent. Electron‐beam‐initiated cross‐linking of the sheets was carried out at a dose of 40 kGy, ...

Development of a molecularly imprinted polymer for selective extraction of bisphenol A in water samples

01-Jun-2010 | Canale, Francesca; Cordero, Chiara; Baggiani, Claudio; Baravalle, Patrizia; Giovannoli, Cristina; Bicchi, Carlo, Journal of Separation Science, 2010

A cross-linked methacrylate molecularly imprinted polymer (poly-4-vinylpyridine-co-trimethylolpropane-trimethacrylate) selective for bisphenol A (BPA) was synthesized, using a fluorinated BPA derivative (4,4[prime]-(hexafluoroisopropylidene)-diphenol) as a mimic template, and applied to the ...

Thioxanthone−Fluorenes as Visible Light Photoinitiators for Free Radical Polymerization

18-May-2010 | Gorkem Yilmaz; Binnur Aydogan; Gokhan Temel; Nergis Arsu; Norbert Moszner; Yusuf Yagci, Macromolecules, 2010

Two thioxanthone derivatives with fluorene additional chromophoric groups, namely thioxanthone−fluorenecarboxylic acid (TX-FLCOOH) and thioxanthone−fluorene sodium carboxylate (TX-FLCOONa), as visible light absorbing oil- and water-soluble photoinitiators, respectively, were synthesized and ...

Synthesis and properties of crosslinked waterborne polyurethane

14-Apr-2010 | Lei Wang, Yiding Shen, Xiaojuan Lai, Zhongjin Li, Min Liu, Journal of Polymer Research, 2010

Waterborne polyurethane prepolymer was prepared by the reaction of isophorone isocyanate(IPDI), polyether polyol(PTMG), dimethylol propionic acid(DMPA) and trimethylol propane(TMP), which was modified by silicane coupling agent(APTES) to form highly crosslinked polyurethane emulsion. The films of ...

Synthesis and photoinitiating behavior of hyperbranched polymeric photoinitiators bearing coinitiator amine

29-Jan-2010 | Hu, Lihua; Asif, Anila; Xie, Jianda; Shi, Wenfang, Polymers for Advanced Technologies, 2010

Abstract A series of benzophenone (BP)‐terminated hyperbranched polyester (BoltornTM P1000), bearing amine moieties as synergists by reacting with piperidine, were synthesized as yellowish liquids with low viscosity, and used as polymeric photoinitiators (HPPIs). For comparison, acrylate groups ...

Preparation of polymeric microcapsules enclosing microbial cells by radical suspension polymerization via water-in-oil-in-water emulsion

27-Jan-2010 | Takayuki Takei, Kaoru Ikeda, Hiroyuki Ijima, Koei Kawakami, Masahiro Yoshida, Yasuo Hatate, Polymer Bulletin, 2010

Polymeric microcapsules enclosing Saccharomyces cerevisiae were prepared by radical suspension polymerization via water-in-oil-in-water emulsion. Trimethylolpropane trimethacrylate and 2,2′-azobis(4-methoxy-2,4-dimethylvaleronitrile) were used as monomer and radical initiator, respectively. A ...

Synthesis and characterizations of waterborne polyurethane modified with 3-aminopropyltriethoxysilane

08-Jan-2010 | Lai Xiaojuan, Li Xiaorui, Wang Lei, Shen Yiding, Polymer Bulletin, 2010

Waterborne polyurethane (WPU) was prepared by the reaction of isophorone isocyanate (IPDI), polyether polyol (PTMG1000), dimethylol propionic acid (DMPA), and trimethylol propane (TMP) and 3-aminopropyltriethoxysilane (APTES) as coupling agent. The films of the WPU were prepared by casting ...

A novel process for holographic polymer dispersed liquid crystal system via simultaneous photo-polymerization and siloxane network formation

15-Feb-2007 | Yeong Hee Cho, Yusuke Kawakami, Silicon Chemistry, 2007

Formation of transmission holographic polymer dispersed liquid crystal gratings was studied for matrix components of trimethylolpropane triacrylate:trimethoxysilylmethyl methacrylate:1-vinyl-2-pyrrolidone (reactive diluent) in the range from 80:10:10,wt% to 10:80:10,wt% and E7 as nematic liquid ...
