Abstract
An antimicrobial substance containing an ethylene copolymer as an active ingredient and an antimicrobial resin composition containing the ethylene copolymer are disclosed. The ethylene copolymer comprises from 40 to 95% by weight of ethylene, from 5 to 60% by weight of at least one dialkylaminoalkylacrylamide comonomer represented by formula (I): ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl group: R.sub.2 and R.sub.3, which may be the same or different, each represents an alkyl group having from 1 to 4 carbon atoms; and n represents an integer of from 2 to 5, and up to 20% by weight of one or more of other ethylenically unsaturated comonomers, and has a number average molecular weight of from 5,000 to 50,000.
