How to precipitate the polymer from the solution system?

I made a co-concentration of N-4-ethylene-N, N-dilate, and styrene. Reference patents: A method of oxygen-based oxygen-based catalytic layer and their preparation methods based on polycomic liquid.However, the sedimentation method of the literature (the ethanol/water of the ice bath (the ethanol/water \u003d 1: 4), drip the reactive solution into the sediment, stir it while dripping, but it generates orange sticky things, sticks to the straw on the strawCan't get it, there is no way to centrifug and draw.Is there any problem with this precipitation method, and is there any other way?Ask you to give menons, grateful!
If there is a great god, you can summarize the method of precipitating the polymer from the solution system in detail. It is better to make other polymers.@Bionics@@@
