A series of silica modified photoresists had been successfully developed through incorporation of a particular nanoparticles suspension. Photoresist binders based on benzyl methacrylate-methacrylic acid-2-hydroxyethyl methacrylate copolymers, were synthesized by radical polymerization The acid value, viscosity, mol. weight and thermal properties of the binders were measured. Then, surface-modified silica particles prepared by the sol-gel method were introduced to the photoresist. Because the modified silica particles contained considerable amount of reactive double bonds (C=C) on their surfaces, they would react with the polyfunctional monomers in the photoresist to form an organic-inorganic nanohybrid. Fourier transform IR spectrometer was used to analyze the evolution of chem. bonds at various stages of the preparation process. Thermal analyses including thermal gravimetric analyzer, differential scanning calorimeter and thermo-mech. analyzer were used to evaluate the level of enhancement on thermal and dimensional stabilities of the photoresist due to silica incorporation. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Electric Literature of C7H14O3).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Electric Literature of C7H14O3
