Patent ID: 8470351

Claim:
A solid antimicrobial composition consisting of: a) a polymeric material that is solid at room temperature and molten at elevated temperatures and, embedded therein, b) a compound represented by formula (I): R 1 —Y 1 —X—Z—(X—Y 2 —R 2 ) n a B −c (I) wherein: Z represents a modified polyol having more than one primary hydroxyl group in its unmodified state, wherein at least two of the primary hydroxyl groups have been replaced by R 1 —Y 1 —X or R 2 —Y 2 —X groups; X represents 1,4-diazoniabicyclo[2.2.2]octane; Y 1 and Y 2 independently represent hydrocarbon chains comprising a minimum of 10 carbon atoms and a maximum of 24 carbon atoms; R 1 and R 2 independently represent H, halo, or OR 3 ; R 3 represents H or R 4 ; R 4 represents —C(O)R 5 or R 6 ; R 5 represents H or a hydrocarbon group comprising a minimum of 1 carbon atom and a maximum of 4 carbon atoms; R 6 represents a hydrocarbon group comprising a minimum of 1 carbon atom and a maximum of 4 carbon atoms; n represents a number up to m−1 wherein m represents the number of primary hydroxyl groups in the unmodified polyol; B represents an anion; a represents an integer; and c represents 1−3; wherein a×c=2n+2.
