发明人：HIGASHIDE WENDY M; CHO KWANG MYUNG; RABIZADEH SHAHROOZ
权利人:EASEL BIOTECHNOLOGIES LLC
摘要:An improved process for alcohol production includes microbial fermentation using a genetically modified microorganism to produce substantial quantities of aldehydes that are stripped from the fermentation medium and condensed. So produced aldehydes are converted in an ex vivo process to corresponding alcohols.

标题:Latex for coatings having improved flexibility
发明人：SRAIL RICHARD E; BURROWAY GARY L
权利人:GOODYEAR TIRE & RUBBER
摘要:This invention relates to the synthesis of a latex which can be formulated into coatings having improved flexibility and good water resistance. Coatings of this type are particularly useful in roof coating applications because they offer excellent flexibility, excellent ultra-violet light resistance, and good water resistance. The subject invention more specifically discloses a process for producing a neutralized latex that is useful in the manufacture of water reducible coatings which comprises: n (1) free radical aqueous emulsion polymerizing, at a pH of less than about 3.5, a monomer mixture which comprises, based on 100 weight percent monomers: (a) from about 30 to about 70 weight percent vinyl aromatic monomers, (b) from about 25 to about 65 weight percent of at least one alkyl acrylate monomer, (c) from about 1 to about 5 weight percent of acrylic acid, and (d) about 0.4 to about 3 weight percent methacrylic acid, in the presence of about 0.2 to 0.4 phm at least one sulfonate surfactant and in the presence of about 4 to 8 phm of at least one nonionic surface active agent having a hydrophile-lipophile balance number which is within the range of about 12 to about 20 to produce a latex; and n (2) neutralizing the latex with ammonia to a pH which is within the range of about 7 to about 10.5 to produce the neutralized latex.

摘要:This invention relates to the synthesis of a latex which can be formulated into coatings having improved water resistance for both moisture vapor transmission and water spotting. Coatings which are formulated with the latex of this invention are particularly useful for coating metal substrates because they provide excellent rust and corrosion resistance. The subject invention more specifically discloses a process for producing a neutralized latex that is useful in the manufacture of water reducible coatings which comprises: (1) free radical aqueous emulsion polymerizing at a pH of less than about 3.5 a monomer mixture which comprises, based on 100 weight percent monomers: (a) from about 45 to about 85 weight percent vinyl aromatic monomers, (b) from about 15 to about 50 weight percent of at least one alkyl acrylate monomer, and (c) from about 1 to about 6 weight percent of at least one unsaturated carbonyl compound; in the presence of about 0.5 to 4.0 phm at least one phosphate ester surfactant and in the presence of about 0.5 to 4.0 phm of at least one water insoluble nonionic surface active agent to produce a latex; and (2) neutralizing the latex with ammonia to a pH which is within the range of about 7 to a bout 10.5 to produce the neutralized latex.
