Abstract: The invention provides a back sheet including a water-impermeable sheet and a film firmly bonded to each other and exhibiting excellent adhesiveness to an EVA encapsulant layer of a solar cell module even without corona discharge treatment on the film surface. The back sheet of the invention is a back sheet for solar cell module, including a water-impermeable sheet and a film. The film is disposed on at least one side of the water-impermeable sheet and is formed from a coating containing a fluorine-containing copolymer. The fluorine-containing copolymer contains a C2-C3 perhaloolefin structural unit, a vinyl acetate structural unit, a hydroxy-containing vinyl monomer structural unit, and a carboxy-containing monomer structural unit.

Abstract: The present invention relates to a process for preparing an aqueous dispersion of a vinyl acetate polymer comprising the step of polymerizing vinyl acetate under emulsion polymerization conditions in the presence of a chain transfer agent which is a hypophosphite salt or X—R1—SH, where R1 is a C1-C4 alkyl group and X is sulfonate, hydroxyl, sulfate, phosphate, phosphonate, carboxylic acid or a salt thereof, or C1-C3-alkyl carboxylate. The process provides a way of lowering the viscosity of the vinyl acetate polymer at a given solids content.

Abstract: The invention relates to a process for the manufacture of α,α-branched carboxylic acids vinyl esters comprising the following steps: isomerising and converting an olefin feed with CO and water under Koch reaction conditions to make an acid with a ratio of Non Blocking isomers (NB) versus Blocking isomers (B) of NB/B above 1.5, wherein a blocking isomer has always a tertiary carbon atom in alpha position of the carboxylic acid and in the beta position of the carboxylic acid, whereas a non-blocking isomer has primary carbon atoms in the beta position of the carboxylic acid converting the resulting acid into a vinyl ester.
