ROCLOR Resins and Plasticizers for Chlorinated Rubber Technical Bulletin 0-124 May, 1957 Monsanto Chemical Company, Organic Chemicals Division, St. louis 1,Mo. Resins and PlastAiciRzeOrsCfLorOCRhlorinated Rubber Jf Monsonlo TeMchanyi,ca1l9B57ulletin 0-124 Introduction N/lonsanto produces a series of chlorinated biphenyls and polyphenyls identified by the trademark Aroclor for use as plasticizers and resins for chlorinated rubber base lacquers, Varnishes and paints. These protective coatings are fire resistant, corrosion resistant, chemical resistant (to acids, alkalies and water), and have good electrical insulating properties. W h e n properly pigmented, these coatings have good weatherability. Chlorinated rubber films plasticized with an Aroclor grip common structural materials in strong adhesive bonds. Addition of an Aroclor improves the flexibility and life of chlorinated rubber and plastic coatings. Ih e formulations suggested in this bulletin are common in commercial practice. They are given as a starting point or guide in developing formulations that expand the outstanding qualities of these compounds. 905992 Afotlcr; Monsanto'Trademark. Rcj. U.S. Pat. Off.

Aroclor 124S is a bi phenyl with 48 per cent chlorination. Aroclor 5460 is a terphenyl with 60 per cent chlorination. Two special mixtures are: Aroclor 4465--a 60:40 mixture (biphenyl to terphenyl)with 65 per cent chlorination. Aroclor 2563-- a 75:25 mixture (biphenyl to terphenyl)with 65 per cent chlorination. The physical properties of the Aroclor plasticizers vary graduallywith the degree of chlorination. At low percentages of chlorine, such as Aroclor 1221 and 1232,the compounds are clear and very.fluid. At 42 per cent they resemble vegetable oil; at 48 per cent they thicken slightly and look more like a medium-grade mineral oil. At 54 per cent chlorine, the compounds are quite viscous; if a bottle containing them is turned upside down, the bubble rises slowly to the top. At higher percentages, the biphenyls become gumlike, and a fingerprint on the surface lasts several day's. Then at 68 per cent chlorine, the. range is complete; Aroclor 1268 is a white powder. The terphenyls (Aroclor. 5442 and 5460) are both yellowish solids: Tbe gradual change in physical properties often allows a processor to select a plasticizer particularly suited for his operation. For example, if he wants to dry mix the plasticizer, Aroclor 1268 could be used. I: melts at higher processing temperature and can act as a solvent-plasticizer. 100037 3- - 905995 Toxicity Animal toxicity studies and 20 years of manufacturing and use experience indicate that Aroclor compounds are not serious industrial health hazards. If the materials are heated to volatilization, ventilation should be pdSrovthideedArtooclporrevcoenmtpionuhnadlas.tion of vapors. This is true of other major components of the formulation as well Repeated or prolonged shin contact should be avoided although there are few instances of skin irritation. sHanutmoanwinpatfcuhrnitsehstsinwfoitrhmaftiinoinsheodn psrpoedcuifcicts AcroonctlaoirnicnogmAprooucnlodrs cuopmonporuenqduseshtave shown no irritation.
