The present disclosure describes a method for forming microporous membranes. More specifically, vapor induced phase separation techniques are used for forming multizone microporous membranes having improved material throughput.

Microporous membrane and method for forming

This disclosure provides (meth)acryloyl pressure-sensitive adhesive foams and foam articles having one or more of the following properties: small cells, uniform cell sizes, pressure sensitive adhesive compositions, compliance to irregular substrates and vibration damping, and shock absorbing properties.

(Meth)acryloyl pressure-sensitive foam adhesives

A method for forming a microporous membrane having a microstructure is described. Dope and coagulant formulations are simultaneously cast, where the coagulant formulation diffuses into the dope formulation through an interface effecting a phase inversion forming a microstructure.
