Polyesterimide-phenol formaldehyde

PontBtixan of miscible poli lends of phenol-formaldehyde (P-F) resins and polyesterimide (PEI) is ej ected from their polar nature. Miscibility in this system probably arises from the interaction between ester grov5>s of polyesterimide (PEI) with the phenolic hydroj ls and ether linkages, present in P-F resin. The structural similarity due to the presence of diphenylenanethane moiety CHo-< oV) in both the polymers may also play a role... [Pg.262]

On the contrary, under oxidative conditions, the secondary l dKM l groi p formed by the partial oxidation of the methylene group of phenol-formaldehyde resin is likely to react with metl -lol group of polyesterimide. The schane of reaction m be shown as in (Scheme IV). The -CH2(ffl group of the polyesterimide may be either N- nethylol group of C-methylol group. [Pg.288]
