A study on the Graft-Copolymerization of 2-Acryloyloxyethyl Acid Phosphate onto Natural Rubber Chadchai Sorarutayangkoor1,a, Jirapong Boonyasiri2,b and Jitladda Sakdapipanich1,2,c 1Institution of Molecular Biosciences, Mahidol University, Salaya Campus, Nakornpathom 73170, Thailand 2Department of Chemistry and Center of Excellence for Innovation in Chemistry, Faculty of Science, Mahidol University, Bangkok 10400, Thailand atomscpo@gmail.com, bpoon_kus34@hotmail.com, cjitladda.sak@mahidol.ac.th Keywords: graft-copolymerization, natural rubber, 2-acryloyloxyethyl acid phosphate Abstract Nowadays, natural rubber (NR) is one of the most important agricultural product of Thailand, which is an important substance with special characteristics such as mechanical properties, excellent strength, and low heat build-up.
However, NR is also known to have inferior properties such as weathering, poor ozone and oil resistance due to its unsaturated hydrocarbon chain structure and non-polarity.

Introduction Because of their attractive luminescence and structure properties [1], tungstates have been intensively studied and applied in many fields such as lasers, fluorescent lamps and scintillators during the past decades.
As a representative example, CaWO4 with the scheelite structure, a buildup of Ca2+ and WO42 groups with the coordination number of eight for Ca2+ and four for W 6+ [2-4], is considered to be highly functional materials due to its intriguing luminescent properties [5-7].
Yttrium (or gadolinium) tungsten silicate RE2SiWO8 (RE=Y or Gd) is isomorphous with the scheelite CaWO4, and the Si4+ occupy the tetrahedral W 6+ sites of the scheelite structure in an ordered way [8].
This corresponds to the (112) plane of the scheelite structure.

Characterization of Indium Oxide Nanoparticles Prepared by Soft Chemistry Route E.
One of the most used soft-chemistry techniques for the synthesis of nanostructures is the precipitation of a soluble salt followed by thermal decomposition of the intermediate material to oxide.
All these patterns may be indexed as cubic bixbyite-type structure (space group Ia3) characteristic of indium oxide.

The structure of CT1 determined by X-ray diffraction are illustrated in fig 2 and fig3 Fig2 Molecular Structure of CT2 Fig3 Crystal packing arrangement of CT2 In fig3 we can see the black molecular and red molecular is stereoisomer and the Frank constant of this crystal is 3, which mean the molecules in one cell have different geometric structure.
The calculation result of CT2 optimistic geometric structure of CT2 (fig4) shows that the Fig4 Optimistic Geometric structure of CT2 The atom C6, C37, C40, and N36 is not in a plant.
The structure of CT1 test of X-ray diffraction also shows the optical isomer directly.
