Abstract
Disclosed is an elastomeric article comprising the cross-linked, polymerized product of (i) a quaternary ammonium compound having the formula N.sup.+ R.sub.4 X.sup.- wherein at least one of the R groups is unsaturated alkyl and the remaining R groups alkyl or aryl and X is halogen or a small anion with (ii) a free-radical co-polymerizable compound.
Claims29
An elastomeric article comprising the cross-linked, polymerized product of (i) a quaternary ammonium compound having the formula N.sup.+ R.sub.4 X.sup.- wherein at least one of the R groups is a hydrophobic unsaturated alkyl and the remaining R groups are hydrophobic alkyl or aryl and X is halogen or a small anion with (ii) a free-radical co-polymerizable compound, wherein the product is complexed with iodine.
A process for making an elastomeric article comprising the steps of:
- (a) polymerizing (i) a quaternary ammonium compound having the formula N.sup.+ R.sub.4 X.sup.- wherein at least one of the R groups is a hydrophobic unsaturated alkyl and the remaining R groups hydrophobic alkyl or aryl and X is halogen or a small anion with (ii) a free-radical co-polymerizable compound,
- (b) forming the article from the resulting polymer,
- (c) cross-linking the resulting polymer, and
- (d) complexing the resulting article with iodine.
A process for making a polymer comprising the steps of
- (a) polymerizing (i) a quaternary ammonium compound of the formula ##STR8## wherein --Y is --OH or --NH.sub.2, R.sup.1 and R.sup.2 are independently alkyl or aryl, X is halogen or a small anion, and n is an integer from 0-50 with (ii) a condensation co-polymerizable compound,
- (b) cross-linking the resulting polymer to make an article, and
- (c) complexing the article with iodine.
A composition comprising a polymer having repeating units of the formula ##STR9## or ##STR10## or ##STR11## or ##STR12## or ##STR13## wherein R.sup.1 and R.sup.2 are independently alkyl or aryl, X is halogen or a small anion, and n is an integer from 1-50.
