Abstract

An antimicrobial polymerizable composition comprising an ethylenically unsaturated monomer, a specific monomer having antimicrobial activity and a polymerization initiator. The composition gives, upon polymerization, a polymer having permanent antimicrobial property, which is very useful for medical articles, in particular dental materials.

Independent Claims | See all claims (3)

  1. 1. A polymerizable composition comprising an ethylenically unsaturated monomer, at least one di- or trifunctional monomer in an amount of 0.01 to 50% by weight selected from the group represented by the following formulas II and III and having antimicrobial activity, and a polymerization initiator ##STR19## wherein R.sub.1 represents a hydrogen atom or a methyl group, R.sub.2 represents an alkylene group having 2 to 18 carbon atoms, X represents an oxygen atom, a sulfur atom or an imide group and Y' and Y" represent any one selected from the following respective formulas: ##STR20## wherein R.sub.3 represents a hydrogen atom or an alkyl group having 1 to 18 carbon atoms, R.sub.4 represents a methyl group, an ethyl group or a hydroxyethyl group and Z represents a chlorine atom or bromine atom.
  2. 2. An antimicrobial crosslinked copolymer obtained by polymerizing a mono- or multifunctional ethylenically unsaturated monomer and an antimicrobial monomer represented by the above formula II or III.
