PhenolFormaldehyde Products

Examples are the sulfonating of polyethylene film with chloro-sulfonic acid (60) the sulfonating of sheets of phenolformaldehyde resin (77) the treatment of a film consisting of polystyrene and polyvinylchloride with concentrated sulfuric acid (4) the sulfonating of films consisting of aliphatic vinylpolymers with chlorosulfonic acid (125) the sulfonating of copolymers of a monovinyl- and a polyvinyl compound (30). Also are used copolymers of aromatic monovinyl-compounds and linear aliphatic polyene hydrocarbons (3) copolymers of an unsaturated aromatic compound and an unsaturated aliphatic compound (76), and of reaction products of poly olefines and partially polymerized styrene (173). 

The products discussed above touch us in every moment of our lives. We wake in the morning to an alarm clock in a polystyrene case we arise from our polyester blend sheets and slip on a pair of slippers glued with polyurethane glue. We flip the polymethylmethacrylate light switch and walk across a Nylon carpet to the bathroom. Our polymethylmethacrylate toothbrush is sitting on the Formica counter top. It has Nylon bristles. The soap we use to wash our face may be hydrocarbon derived sodium lauryl sulfate. We walk to the kitchen with polyvinyl chloride floors and sit at a Formica table. The polyethylene milk carton is at hand to supply the milk for the cereal stored in the polyethylene bag. It is eaten from a urea formamide bowl. The frying pan has a phenolformaldehyde plastic handle and a Teflon interior coating. 

An interesting method, used by A. Davis [213] to synthesize fragments of phenolformaldehyde resins, can be used to produce the products under consideration. By heating an alcoholic solution of a mixture of cyclohexanone with p-hydroxybenzaldehyde in the presence of sodium hydroxide, the authors produced the intermediate 2,6-bis-hydroxy-benzylidenecyclohexanone, which was converted to a dialkylenetriphenol after hydrogenation with heating with Pd/C ... 

When the blends of polyesterimide-novolac and polyesterimide-resole are heated separately to 300 C or above and 200 C or above, respectively, it is found that the heated products are insoluble in solvents like N,N-dimethyl foimiamide (DMF), l methyl-pyrroli-done (NMP), 1,4-dioxane, m-cresol, etc. The insolubilil of the blends after heating is believed to be due to crosslinking. It is very likely that the phenolformaldehyde resin component of the polyblend provides the crosslinks. It has been observed that the blend containing as low as 10% P-F resin is capable of cross-linking.
