Abstract
A latex useful as a binder for paper, nonwovens, and textiles is prepared by copolymerizing in aqueous emulsion using a redox initiator at 5.degree. C. a mixture of 35 to 60% weight of a conjugated diene monomer and from about 30 to 65% by weight of a vinyl aryl monomer. Additional improvements can be obtained by incorporating in the mixture a small percentage by weight of copolymerizable monomers such as acrylic acid, methacrylic acid, itaconic acid and/or a functional type monomer having an activatable methyl, ethyl, propyl or butyl ester group and a vinyl group.
