Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
57 words
A composition comprising a plasticizer suitable for use as a polymer processing aid and, in an amount at least sufficient to impart microbiocidal properties to the composition, a microbiocidal compound which is present in the composition as the solute in an aryl alkanol solvent, said microbiocidal compound being selected from the group consisting of phenoxarsines and phenarsazines.
Claim 2
Dependent Claim
57 words
A composition comprising a plasticizer suitable for use as a polymer processing aid and, in an amount at least sufficient to impart microbiocidal properties to the composition, a microbiocidal compound which is present in the composition as the solute in an aryl alkanol solvent, said microbiocidal compound being selected from the group consisting of phenoxarsines and phenarsazines.
