标 题 :Latex for coatings having reduced blushing characteristics

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 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.

标题 :Polymer arrays for biofilm adhesion testing

摘要:This invention relates to a method of screening arrays of polymers having pre-determined surface energies. The polymer arrays of the present invention can be used to screen for microorganism adherence. More specifically the arrays can be used to screen for adherence of particular bacteria or fungi to particular polymers in the array. Furthermore, this invention relates to a method combining in-situ polymer synthesis with physico-chemical characterisation of the resulting polymer array and subsequent biological assays of bacterial or fungal adherence. This allows for high throughput screening and characterisation of candidate polymers which are not susceptible to bacterial or fungal adherence or which can be used to support bacterial or fungal adherence where such is required. The arrays can also be used to screen for inhibition or promotion of biofilm formation.
