ABSTRACT:
A melt-extrudable composition which includes a thermoplastic polyolefin and a siloxane quatemary ammonium salt additive. The additive can be either of two general classes: (1) a trisiloxane having a pendent quatemary ammonium group and a molecular weight of from about 600 to about 1,700; and (2) an ABA-type siloxane having a polydispersity of up to about 3.0 and a weight-average molecular weight of from about 800 to about 2,000, in which a central siloxane moiety is terminated at each end by a quatemary ammonium salt group. The anion in general can be any anion which does not adversely affect the thermal stability of the salt. The siloxane quatemary ammonium salt possesses antimicrobial properties. Upon melt extruding the thermoplastic composition to form fibers and nonwoven webs, or other shaped artides, the surfaces of such shaped artides exhibit antimicrobial properties.
