A process for producing protective-colloid-stabilized polymers based on ethylenically unsaturated monomers in the form of water-redispersible powders, by producing aqueous dispersions of protective-colloid-stabilized polymers based on ethylenically unsaturated monomers by polymerization of one or more ethylenically unsaturated monomers in an aqueous medium and drying said dispersions in the presence of one or more drying aids. The drying aids include a) one or more inorganic salts selected from the group of alkali metal sulfates and alkali metal sulfites and b) optionally one or more water-soluble organic polymers. The inorganic salts a) are present in the aqueous dispersions of the protective-colloid-stabilized polymers based on ethylenically unsaturated monomers in dissolved form after all drying aids have been added. The inorganic salts a) are employed as drying aids to an extent of 25% by weight based on the total weight of the drying aids.

The invention is related to a process for synthesizing a sustainable aviation fuel composition. The process comprises providing a reaction mixture comprising a first compound that is at least one of mevalonolactone, mevalonic acid, mevalonate salt, dehydromevalonic acid, dehydromevalonate salt, levulinic acid, levulinate salt, caproic acid, caprolactone, caproate salt, or combinations thereof. The process then involves converting the first compound in the reaction mixture to provide a first intermediate comprising isoprene. Then, the isoprene in the first intermediate is reacted in the presence of a first heat transfer agent to provide a second intermediate comprising terpenes. Finally, the second intermediate is allowed to react to in the presence of a second heat transfer agent, or alternatively in neat conditions, and optionally in presence of a catalyst to provide the sustainable aviation fuel composition. The sustainable aviation fuel composition made available from the process of the invention is found to be substantially devoid of Sulphur, olefins, MAHs and PAHs while retaining high energy density. Such qualities are deeply appreciated for use of such sustainable aviation fuel compositions as rocket propellants.

The invention is related to a process for synthesizing a polymer composition. The process comprises providing a reactant mixture for conducting multistep reactions to produce products with high selectivity and yields. The reactant mixture comprises a first reactant composition comprising at least one precursor compound for conversion to a hydrocarbon molecule with at least one carbon carbon double bond; a heat transfer fluid; and at least one stabilizer. The process then involves reacting the first reactant composition in the presence of a heat transfer agent, following by purification to provide a monomer composition. The monomer composition may then be optionally fractionated. Then, the monomer composition is polymerized to provide the final polymer composition.
