A study is described of the properties of vulcanized films obtained from a mixture of latices of solid and liquid butadiene/(36-40%) acrylonitrile rubber by the ionic deposition method. The content of liquid polymer was 0-30 parts per 100 parts of solid rubber. The maximum strength of latex films is attained with a content of liquid polymer of 3-5 parts. With increase in the amount of liquid polymer there is an increase in the autohesion strength of the system.
