Claims24
A microporous polymeric composition comprising 60% to 90% by weight of a matrix polymer selected from at least one of substituted polyacetylenes and polymers of intrinsic microporosity (PIMs) and having a fractional free volume of at least 0.1 and dispersed particles comprising 5% to 25% by weight of the microporous polymeric composition of hypercrosslinked polymer comprising optionally substituted aryl groups (Ar) covalently linked by methylene bridging groups (CH2) providing a link with repeating units —(Ar—CH2—Ar—CH2)n- wherein n is the number of repeating units.
A microporous polymeric composition comprising a matrix polymer having a fractional free volume of at least 0.1 and dispersed particles comprising hypercrosslinked polymer comprising optionally substituted aryl groups covalently linked by methylene bridging groups (CH2) wherein the hypercrosslinked copolymer is obtained by a friedel crafts catalysed polymerisation of either:
- (a) a substituted aryl monomer comprising at least two chloromethylene groups;
- or
- (b) an optionally substituted aryl monomer with an external cross-linker.
