An efficient palladium-cocatalyst system for vinylation of unsaturated carboxylic acid has been exploited,among which aliphatic amines(ALA)are firstly used as cocatalysts.
Self-preparation polymerizable macromolecular surfactant HTP and acrylate monomer were used to prepare the amphiphilic polymer by soap-free microemulsion pentamer copolymerization.
Phragmoplast of coil coating has been prepared by free radical polymerization and by using acrylic acid,methyl methacrylate,butyl acrylate as the raw materials.
We found that the poly methacrylates prepared by modified microemulsion polymerization have properties of high glass transition temperature (Tg) and rich syndiotacticity.
The development and application of organosilicone modifying acrylic resin,polyurthane,nitrocotton and casein etc. in leather chemical materials at home and abroad are introduced.
Ethyl phenylacrylate intermediate bringing a double bond was introduced first,which is subsequently transformed into triketone and then DCM was obtained with high purity.
It is possible to predict and controll the conversion rate of esterifications such as acrylic acid with dodecanol,tetradecanol and hexadecanol by this equation.
