Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
76 words
A process for imparting microbiocidal properties to a polymer composition comprising adding to the polymer composition a liquid microbiocidal solution comprising an aryl alkanol and, in an amount sufficient to impart microbiocidal properties to the polymer composition, a microbiocidal compound dissolved in the aryl alkanol, said microbiocidal compound being selected from the group consisting of phenoxarsines, phenarsazines, maleimides, isoindole dicarboximides having a sulfur atom bonded to the nitrogen atom of the dicarboximide group, and isothiazolinone compounds.
Claim 2
Dependent Claim
76 words
A process for imparting microbiocidal properties to a polymer composition comprising adding to the polymer composition a liquid microbiocidal solution comprising an aryl alkanol and, in an amount sufficient to impart microbiocidal properties to the polymer composition, a microbiocidal compound dissolved in the aryl alkanol, said microbiocidal compound being selected from the group consisting of phenoxarsines, phenarsazines, maleimides, isoindole dicarboximides having a sulfur atom bonded to the nitrogen atom of the dicarboximide group, and isothiazolinone compounds.
