摘要
Cigarette filters, methods for making cigarettes and methods for smoking cigarettes are provided, which involve the use of an unfunctionalized porous polyaromatic resins, which is capable of removing at least some of at least one gas phase constituent from mainstream smoke through sorption. The unfunctionalized porous polyaromatic resin may be a polymerization product of non-polar styrene and divinyl benzene. Various gas phase constituent can be removed from mainstream tobacco smoke, such as dienes, furans, pyrroles, aromatics and ketones, for example. The cigarette filters and cigarettes can provide low resistance-to-draw and/or high total particulate matter delivery. Additionally, the unfunctionalized porous polyaromatic resin may further include flavorant(s).
