Tobacco smoke filter material and process for the preparation thereof |
摘要 |
Disclosed are materials and compositions effective for the selective removal of gaseous aldehydes from tobacco smoke. The materials and compositions comprise tobacco smoke filters comprising a fibrous material or fibers of a polymeric material containing covalently-bonded acetoacetoxy residues. The fibrous material or fibers are capable of reacting with and removing aldehydes present in tobacco smoke. Also disclosed are processes for the preparation of fibrous materials and fibers of a polymeric material containing covalently-bonded acetoacetoxy residues and methods for the removal of a gaseous aldehyde from tobacco smoke by contacting tobacco smoke with the aforesaid fibrous materials or fibers containing covalently-bonded acetoacetoxy residues.
