Storage behaviour of this latex and its vulcanizates was studied in comparison to normal centrifuged latex (cenex). Changes in raw latex properties such as volatile fatty acids, mechanical stability time, potassium hydroxide number and zinc oxide viscosity were comparable for both the latices. But the change in EP content for low protein latex vulcanizates was from 68 to 88 ?g/dm2 where as for the cenex, the increase was from 150 to 368 ?g/dm2. Physical properties of latex film vulcanizates were more or less unaffected by storage
