Poly(vinyl cinnamate) average Mn 40,000, powder - Preparation Method
Open Data Verified Data
There are two preparation methods.
- The pyridine method was invented by the U. S. Company, O. K. First, the polyvinyl alcohol is refined to narrow its molecular weight distribution, then the refined polyvinyl alcohol is added to pyridine solvent at 95~100 ℃, and cinnamoyl chloride is added dropwise at 50 ℃ to react with it, after several hours of reaction, the reaction mixture was diluted with acetone, precipitated in water, washed and dried to obtain a finished product.
- The methyl ethyl ketone method was invented by industrial trials in Tokyo, Japan. Dissolve the refined polyvinyl alcohol in warm water, add sodium hydroxide solution, cool to 0 ℃, and then add cinnamoyl chloride dissolved in butanone to the above solution for esterification reaction under vigorous stirring at 0 ℃, the finished product was prepared by post-treatment.

Poly(vinyl cinnamate) average Mn 40,000, powder - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Application | the polymer polyvinyl cinnamate can be made of cyclohexanone, methyl glycol ethyl ether acetate and other solvents to make the film, after exposure, can be used methyl glycol ethyl ether acetate, A solvent such as ethyl methyl acetone and trichloroethylene is developed. The polymer can be developed with toluene. |
| Use | polyethylene cinnamate can be used for printed circuits, nameplate, chemical corrosion, gravure, used as lithographic material |
| preparation | HMPA method: polyvinyl alcohol is dissolved in an aprotic polar solvent such as hexamethylphosphonium, adding cinnamic acid chloride to the homogeneous reaction is a good method, but the solvent is expensive and toxic. In addition, in the cationic polymerization of vinyloxyethyl cinnamate [2], the vinyl ether can be selectively polymerized to obtain [3]. [3] compared with [1], the glass transition point is low, and the photoreactivity and adhesion to the substrate are good. Since a pure product can be produced, it is very useful for a photoresist for high-density integrated circuits. |
