Abstract
A highly porous polymeric material which may be dry or contain an included liquid, for example, a cleaning composition, is reinforced and rendered heat-sealable by the incorporation of thermoplastic fibrous, particulate or foraminous material. The polymeric material is preferably a styrene homo- or copolymer prepared by polymerization of a high-internal-phase emulsion. Sheets of the porous polymer may be sandwiched between two liquid-permeable substrate layers to form a wiping cloth or the like.
