Abstract

A polymer composition containing a polymer (B) obtained by polymerizing a monomer composition containing: a methacrylic acid ester macromonomer (b1) represented by the following formula (1); and another monomer (b2). Also, a porous membrane formed from a membrane forming polymer (A) and the aforementioned polymer composition.

Claims

exact text as granted — not AI-modified
1 . A polymer composition comprising:
 a membrane forming polymer (A); and   a polymer (B) obtained by polymerizing a monomer composition containing a methacrylic acid ester macromonomer (b1) represented by the following Formula (1)   
       
         
           
           
               
               
           
         
         and another monomer (b2), 
         where 
         R and R 1  to R n  of Formula (1) each independently represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group, 
         Z is a terminal group, and 
         n is an integer from 2 to 10,000. 
       
     
     
         2 . The polymer composition according to  claim 1 , further comprising a membrane forming polymer (A). 
     
     
         3 . The polymer composition according to  claim 2 , wherein the membrane forming polymer (A) is a fluorine-containing polymer. 
     
     
         4 . The polymer composition according to  claim 1 , wherein the other monomer (b2) is (meth)acrylic acid or a (meth)acrylate. 
     
     
         5 . The polymer composition according to  claim 1 , wherein a contact angle of pure water on an outer surface of a porous membrane formed from the polymer composition is 75° or less. 
     
     
         6 .- 10 . (canceled)
