Research ArticleOpen accessPhrase in the titleSetting Shrinkage Characteristics of Methyl Methacrylate-Modified Vinyl Ester Polymer ConcreteKi-Bong Choi, Seung-Ho Min, Kyu-Seok YeonThis study evaluated the setting shrinkage characteristics of Methyl Methacrylate (MMA)-modified vinyl ester polymer concrete with different curing ages, MMA contents and curing temperatures. Results have shown that most of the setting shrinkage developed within 24 h after curing initiation. It was also found that an increase in MMA content led to an almost linear decrease in setting shrinkage, indicating … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 17 May 2016 · 8,300 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffects of Curing Temperature and MMA Content on the Working Life of MMA-Modified Vinyl Ester Polymer ConcreteKi-Bong Choi, Seung-Ho Min, Kyu-Seok YeonThe main purpose of this study is to identify the effects of curing temperature and methyl methacrylate (MMA) content on the working life of vinyl ester polymer concreteusing MMA as a monomer, N,N-dimethyl-p-toluidine (DMP) and methyl ethyl ketone peroxide (MEKPO) as initiators and cobalt naphthenate as a promoter. The results have shown that the working life of vinyl ester polymer … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 23 Jan 2017 · 7,962 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCustomer-Made 3×3 Polymer Optical Fiber Splitter Based on Green Technology using Fusion TechniqueMohammad Syuhaimi Ab-Rahman, Nik Nur Syahirah Mohammad, Hadi Guna et al.Problem statement: Polymer Optical Fiber (POF) has many advantages making it the choice of today’s communication, especially in automotive industry. This communication requires low cost ways for much information to be sent simultaneously. Because of this, using Wavelength Division Multiplexing (WDM) concept, a low cost and green 3×3 POF splitter is fabricated. It is fabricated using cheap and easy-to-find tools … …Journal of Computer Science, Vol. 8, Issue 4 · 11 Feb 2012 · 6,842 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPreparation of Fluorine/Silicon Co-Modified Elastic Acrylate with Low Fluorine and High PerformanceYuan Zhihua, Xia Chunlei, Geng Ziye et al.The methyl acrylate was modified with hexafluorobutyl methacrylate (G02) and vinyl triethoxy silane (A-151) as modified monomers, Methyl Methacrylate (MMA) as hard monomer and Butyl Acrylate (BA) as soft monomer. Pre-emulsification, seed emulsion and semi-continuous synthesis process were adopted to the effects of the preparation process, the ratio of G02 and A-151 modified monomers, the amount of soft monomer and … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 4 Jan 2020 · 7,651 accessesView PDF Cite
