Patent ID: 8399530

Claim:
A process for producing polymer foams which comprises contacting a solution L1 comprising at least one polymerizable compound which polymerizes in a subsequent process stage and a solvent L, and optionally at least one solution L2 comprising a polymerizable compound and a solvent which may be identical or nonidentical to the solvent from L1, with one or more gas(es) G which is/are only partly dissolvable, if at all, in the solvents used, at least one of the solutions comprising an emulsifier or another assistant, to form a foam as a result of development of struts and/or walls by the solutions which enclose the gas G as bubbles, and wherein the solutions and the gas G are contacted under microfluidic process conditions to develop bubbles of the gas G, and wherein polymerization starts in the course of foam formation.
