Abstract
Abstract Compositions are disclosed which comprise resin, generally synthetic resin and a biologically effective amount of ortho-benzyl-para-chlorophenol. Preferred compositions include a phthalic acid derivative plasticizer-solvent to facilitate distribution of the ortho-benzyl-para-chlorophenol throughout the resinous body of articles formed of the composition.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
35 words
In an antimicrobial solid synthetic resinous composition which in the fabrication of articles and films is subjected to relatively high temperature, the improvement consisting essentially of the incorporation of a antimicrobially effective amount of ortho-benzyl-para-chlorophenol.
Claim 2
Dependent Claim
35 words
In an antimicrobial solid synthetic resinous composition which in the fabrication of articles and films is subjected to relatively high temperature, the improvement consisting essentially of the incorporation of a antimicrobially effective amount of ortho-benzyl-para-chlorophenol.
Claim 3
Dependent Claim
19 words
The composition of claim 1 wherein 0.25% to 10.0%, by weight, of ortho-benzyl-para-chlorophenol is present in the resinous composition.
Claim 4
Dependent Claim
21 words
The composition of claim 1 including a particulate inert inorganic diluent to assist in dispersing the ortho-benzyl-para-chlorophenol in the resinous composition.
Claim 5
Dependent Claim
22 words
The composition of claim 1 wherein the relatively high temperature is in the order of about 275° F to about 480° F.
Claim 6
Dependent Claim
30 words
The composition of claim 1 wherein the solid synthetic resinous composition comprises a synthetic resin selected from the group consisting of polyethylene, polystyrene, polystyrene butadiene copolymer, polypropylene and polyvinyl chloride.
Claim 7
Dependent Claim
48 words
An antimicrobial composition of matter capable of withstanding molding temperatures in the order of about 275° F to about 500° F without significant loss of antimicrobial activity, the essential constituents of which are (1) a solid synthetic polymer and (2) at least an antimicrobially effective amount of ortho-benzyl-para-chlorophenol.
Claim 8
Dependent Claim
48 words
An antimicrobial composition of matter capable of withstanding molding temperatures in the order of about 275° F to about 500° F without significant loss of antimicrobial activity, the essential constituents of which are (1) a solid synthetic polymer and (2) at least an antimicrobially effective amount of ortho-benzyl-para-chlorophenol.
Claim 9
Dependent Claim
18 words
The composition of claim 6 wherein 0.25% to 10.0%, by weight, of ortho-benzyl-para-chlorophenol is present in the composition.
Claim 10
Dependent Claim
40 words
A polymeric article of manufacture having antimicrobial properties, subsequent to molding temperatures in the order of about 275° F to about 500° F, comprised of (1) a solid synthetic polymer and (2) at least an antimicrobially effective amount of ortho-benzyl-para-chlorophenol.
Claim 11
Dependent Claim
40 words
A polymeric article of manufacture having antimicrobial properties, subsequent to molding temperatures in the order of about 275° F to about 500° F, comprised of (1) a solid synthetic polymer and (2) at least an antimicrobially effective amount of ortho-benzyl-para-chlorophenol.
Claim 12
Dependent Claim
21 words
The article of manufacture of claim 8 wherein 0.25% to 10.0%, by weight, of ortho-benzyl-para-chlorophenol is present in the polymeric article.
