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:Synthesis of integral skin microcellular polyurethane elatomers by reacting hydroxyl-terminated aliphatic polyesters with symmetrical diisocyanates, prepolymers of these isocyanates such as derived from p,p'-diphenylmethane diisocyanate and an aliphatic glycol and mixtures thereof, these are polymerized in the presence of an organic blowing agent, and one or more plasticizers such as of the formulae further enhancement of the results is brought about by the presence of catalysts and cell regulating agents, such as dimethylpolysiloxanes; the obtained elastomers are useful, such as for shoe soles and in the manufacture of other products, e.g., vibration dampening devices, floatation devices, gaskets and the like.

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.
