Introduction ' Monsanto's Montar polychlorinated polyphenyl compounds resist oxidation, impart (lame rotardance and tackiness to asphaltic, rubber, nnd various synlhctic-rcsin compositions. Those compounds are effective low-cost solid plasticizer binders or tnckifiers for adhesives, mastics, or hot-melt systems in which color is not objectionable. They are readily incorporated in rubber-based paper adhesives when dissolved in a suitable solvent. The chlorinated polyphenyls contribute flame relardar.ee to specialty asphalt products; Montar'tjn concentrations of 30 per cent or more yields products with mstsmtoncewe-flsrne-ouk ***** ' AH Montar products are compatible with polyvinyl chloride at con centrations of up to about 10 pai Is per 100 parts of resin and can be used as extender plasticizers to reduce formulating costs. They bavf been reported to be useful as extenders in epoxy resins, and their structure suggests that they may be useful ns plasticizers for several oilier synthetic resins., Monlaivjcompounty 4nr high-melting, dark, chlorinated /Montee, 1, 0, 3, 1, u) oi-yi-mixture of unchlorinatcd polyphenyls Applications 9 fa fa A&yhall All the Montar products are compatible with asphalt at concentrations up to two parls per part of asphalt.

Mev The emulsifiability of wfr-tbc Montar product^ suggests additional applications in the adhesives field. When 6 percent of an emulsifier was added to a 60 percent solution of Montar in benzene or toluene and the mixture was progressively diluted with water, the emulsion did not break until water dilution reached 160 percent of the original mixture volume.

Vinyls Up to 10 parts of any Montar product can be biended with 100 parts of polyvinyl chloride resin by simple mixing. Celiuloslcs The Montar. products are suggested as potentially useful low-cost extenders for ethyl cellulose. They would also impart flame retardancy where desirable.

Either local exhaust and adequate ventilation or suitable respiratory protection are suggested. Contact with eyes and prolonged or repeated skin contact should be avoided. If skin contact occurs, remove the material by washing with soap and wator. Clothing that becomes soaked with fluids that con tain a Montnr compound should be laundered -- before being worn again. No special handling precautions, other than good industrial practice, is needed for Montar 9, which is not a chlorinated hydrocarbon.
