摘要: In one embodiment is provided a polymer blend of poly(vinyl acetate) (PVAc) and poly(acrylic acid) (PAA), wherein the poly(vinylacetate) is present in an amount ranging between about 20 wt % and about 80 wt %, and poly(acrylic acid) is present in an amount ranging between about 80 wt % and about 20 wt %, based on the total weight of the blend. In another embodiment is provided a fiber produced from this polymer blend, and which has cells therein. In another embodiment is provided a flavorant release material comprising the porous fiber disclosed herein, and one or more flavorants disposed in a longitudinally extending core within the fiber. In another embodiment is provided a polymer fiber membrane containing a hollow, porous fiber formed from the polymer blend disclosed herein. In another embodiment is provided a filter containing the fiber described herein. In another embodiment is provided a process for producing the fibers disclosed herein by addition of the polymers to an extruder or blender, and extruding or melt spinning the mixture into a fiber containing cells therein.
