REMOVING HEAT FROM VINYL ACETATE PRODUCTION BY INTRODUCING LIQUID TO FLUIDISED REACTOR WHICH EVAPORATESKITCHEN, SIMON JAMESBRISTOW, TIMOTHY CRISPINNEWTON, DAVID
This is the same chemistry that is used in the synthesis of other perfluorinated vinyl ether monomers such as PMVE and PPVE. The synthesis of the 3 M monomer, MW = 380, is used to illustrate this reaction sequence; other monomers are prepared by using different perfluoro acyl fluorides: ...
The measurement of thermal conductivity is taken at the solid and liquid phases. Table 2 summarizes the thermal conductivity value of the prepared samples as pure and composite SSPCM (shape-stabilized phase change material/SSPCM). HDPE obtains the highest thermal conductivity at the solid phase. HDP...

This process was also applied to adhesive-free adhesion between a tetrafluoroethylene–perfluoroalkylvinylether copolymer (PFA) and PDMS; subsequently, a translucent PFA/PDMS assembly with strong adhesion was realized together with the PTFE/PDMS assembly. Strong adhesive-free adhesion between fluoropolymers...

(preparation of liquid formulation of film-forming resin) Three parts of the modifier (M4) obtained in Referential Example 4 were added to 100 parts of a methyl ethyl ketone solution (solid content: 30%) of a vinyl chloride/vinyl acetate/vinyl alcohol copolymer resin ("Eslek A", trade name...
As the pour point depressant, there can be used, for example, ethylene-vinyl acetate copolymer, a condensate of chlorinated paraffin and phenol, a condensate of chlorinated paraffin and naphthalene and polymethacrylate copolymer, which are used usually from 0.01% by weight to 5% by weight. The ...
