Versuchsvorschrift

Into an agitated reactor are placed 981 g of a 1900 A butadiene/styrene/acrylonitrile (93/5/2) rubber latex (37.2% solids), 388 g of water, 0.255 g of K2S2O8, and 0.085 g of EDTA.2Na+. The pH of the mixture is adjusted to 3.5 using acetic acid. The mixture is then heated to 65° C. At this point two continuous addition (conadd) feed streams are started and added over a one hour period. One is 72 g of an aqueous stream consisting of 2.12% sodium dodecylbenzene sulfonate. The other stream is 87 g of a monomer mixture of 95.6% ethyl acrylate and 4.4% methacrylic acid. The mixture is heated at 65° C. for 4 hours after the conadd streams are finished. The AgAg particles produced consist of 20% shell, the shell consisting of about 95.6% EA and 4.4% MAA.
