PLASTICIZER
Hooker chlorinated paraffin, trademarked CP-40,® is compatible with a variety of resins, forming films ranging from soft and sticky to tough or rubbery. Among the resins having the most interesting possibilities are polyvinyl chloride, chlorinated rubber, acrylic resins, neoprene, polystyrene and vinyl acetate. CP-40 is a light, honey-colored, viscous liquid averaging 42.5% chlorine. It is soluble in most organic solvents and has a negligible vapor pressure and evaporation rate at room temperature. Plasticizer, M P S ® - 5 0 0 HOW TO IMPROVE A VINYL COMPOSITION
MPS®-500 is a low-cost plasticizer which can add all these properties to your polyvinyl chloride formulations —flame retardance, resistance to water, oil and gasoline, thermal strength, higher tensile strength and flexibility, low migration. It is a stabilized chlorinated ester of a fatty acid and is completely compatible with PVC polymers in ratios as high as 60 parts per 100. MPS-500 is insoluble in water, soluble in chlorinated hydrocarbons, aromatics, aliphatics, alcohols, esters and ketones. C12.4H25.7SH (average) AN INTERESTING POLYMERIZATION MODIFIER
Hooker lauryl mercaptan may be just the modifier you need for use in polymers, organic specialties and vinyl stabilizers. •It will copolymerize with almost any type monomer and is widely used FOR

Polypropylene filled with Dechlorane + Plus and antimony shows no migration when heat aged at 120° C. In addition, color stability due to thermal degradation on mold ing is improved over other chlorinated organic antimony oxide-filled systems.

THREE CURING CATALYSTS FOR RESINS
They are our methyl, butyl and amyl acid phosphates. m These colorless to light-yellow liq uids are excellent curing catalysts and accelerators in resins and coatings. You can use small amounts of butyl acid phosphate, for example, with urea or melamine modified fin ishes to lower curing temperature and improve hardness and durability. All three of these Hooker alkyl acid phosphates provide uniform curing of acid setting resins. They are also used as stabilizers for vinyl plastics. We offer, in addition, lauryl, oleyl and stearyl acid phosphates—white to light-yellow solids and semisolids. Special alkyl acid phosphates can be made for special applications. Dechlorane @ + Plus A NONMIGRATING FIRE-RETARDANT ADDITIVE Dechlorane + Plus is a highly chlo rinated, very stable organic compound with a melting point higher than 350° C. We suggest it as a nonplasticizing fire-retardant additive in thermoplas tic and thermosetting polymeric sys tems where electrical, corrosion or thermal conditions are a factor. You may find it useful in such elas
-CI -CI WHAT CAN YOU DO WITH THESE ACTIVE CHLORINES?
C-56,® hexachlorocyclopentadiene, undergoes substitution and addition reactions to provide a variety of inter esting intermediates. Its derivatives include esters, amides, ketones, diketones, quinones, acetals, nitriles and other halogenated hydrocarbons. Many of its end products find mar kets as insecticides, pharmaceuticals and nonflammable resins. Is there an idea here for you? Many more profitable products await devel opment by men with imagination. The information packed into these short paragraphs still leaves much unsaid on these important chemicals for plastics. For more complete information, in cluding specifications, typical physi cal data, handling and representative reactions, we suggest you send the coupon for data sheets and other literature. If the chemical you need is not here, please write us describing your prob lem. Our specialists will be glad to work with you.
