摘要:
Plant oil-based compounds are provided which possess both low viscosity and high reactive functionality. These compounds are useful in coating and composite applications, as well as related methods. Exemplary compounds can be produced by transesterification of a plant oil triglyceride with a nucleophile reactant, such as a vinyl-functional alcohol, to yield reactive fatty acid-containing monomers.
摘要:
A surfactant for emulsion polymerization which is satisfactory in polymer emulsion stability during polymerization and gives a polymer emulsion which gives a polymer film having satisfactory material properties. The surfactant gives a polymer emulsion which is satisfactory in mechanical stability and chemical stability and which gives a polymer film having satisfactory water resistance. The surfactant comprises at least one member selected among unsaturated compounds which have a pentenyl group having an alkylene oxide added and are represented by the formulae (I), (II), and (VI). Also provided is a process for producing a polymer emulsion which comprises conducting emulsion polymerization with this surfactant composition. (I) (II) [In the formulae, A represents C3-18 alkylene or alkoxymethylethylene (the alkoxy group has 4 to 18 carbon atoms); EO represents oxyethylene; a is a number of 0 to 50 and b is a number of 0 to 200, provided that not both of a and b are 0; and M represents a cation.] (VI) [In the formula (VI), A'O represents C3-18 oxyalkylene; E'O represents oxyethylene; m is a number of 0 to 50; n is a number of 5 to 200; and the m -(A'O)- groups may be the same or different.]
摘要:
A highly fluorinated benzene compound is reacted with acryloyl chloride to yield a fluorinated liquid product which is used to impregnate a reinforcing structure. Upon impregnation, the liquid material is polymerized at about 55 °C to produce a reinforced polymeric structure, which can be a circuit board. The polymer has dielectric constant of about 2.1, which is very low compared to the polymers used presently.
