Describes a method for preparing for subsequent testing dry polymer from anionic stabilized synthetic rubber latices having a volatile unsaturates content of less than 0.5 % (m/m). Applies to a variety of latices, but should be confirmed for individual types. Dry polymer contains residual organic acids or soaps which may affect its properties which should be taken into account in the case of analytical tests. Requires a combined high-speed mechanical stirrer and comminutor, with a totally enclosed motor, and with a stirrer vessel of capacity at least 1000 cm cubed, and a forced-draught oven, capable of being maintained at a temperature between 100 degree C and 125 degree C.
