ABSTRACT:
The separation of hydrocarbon mixtures comprising a polymerizable vinyl containing polyester of the formula I:Each R and R2is independently a C6-C20aromatic residue or a C1-C20aliphatic residue. Each R1is independently hydrogen or C1-C5alkyl; “j” is an integer in the range of 1-1000. Z is a heteroatom or two hydrogen atoms. The invention is also directed to the method of preparing the separation membrane.
