What solvents do PDMAEMA are better for precipitation, laboratory conditions are limited, and there is no frozen dryer

Sinking the post is full of sadness

Under the condition of ice water bath, the orthodoxane is precipitated, you can try

The TG of PDMAEMA is low. The frozen temperature of petroleum ether or nitrogen nitrogen is as low as possible, and the polymerizer droplets are very good. THF dissolves and sediment the operation 2 times to dry. I do that.The DP too small polymer is the same as the foam as the foam.
