Abstract

Abstract The present invention provides a novel antimicrobial polymer composition having superior weatherability and discoloration resistance over those of the prior art. The present invention provides an antimicrobial polymer composition comprising a polymer and an antimicrobial composition comprising an antimicrobial coat of an aluminosilicate on the surface of silica gel, wherein said aluminosilicate contains antimicrobial metal ions, characterized in that said antimicrobial polymer composition further comprises thiabendazole.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 41 words
An antimicrobial polymer composition comprising a polymer and an antimicrobial composition comprising an antimicrobial coat of an aluminosilicate on the surface of silica gel, wherein said aluminosilicate contains antimicrobial metal ions, characterized in that said antimicrobial polymer composition further comprises thiabendazole.
Claim 2
Dependent Claim 33 words
An antimicrobial polymer composition of Claim 1 wherein said antimicrobial metal ions are silver ions and optionally one or two metal ions selected from the group consisting of zinc ions and copper ions.
Claim 3
Dependent Claim 49 words
