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.
We found that the poly methacrylates prepared by modified microemulsion polymerization have properties of high glass transition temperature (Tg) and rich syndiotacticity.
Phragmoplast of coil coating has been prepared by free radical polymerization and by using acrylic acid,methyl methacrylate,butyl acrylate as the raw materials.
The development and application of organosilicone modifying acrylic resin,polyurthane,nitrocotton and casein etc. in leather chemical materials at home and abroad are introduced.
Select the system of copolymerisation,the optimum reactive conditions of temperature and velocity,and the best quantity of emolsifier and initiator of acrylate emulsion thickener.
It is possible to predict and controll the conversion rate of esterifications such as acrylic acid with dodecanol,tetradecanol and hexadecanol by this equation.
