Procedure: A phenolic resin rich in alternating phenolic copolymer block segments was formed by reacting a mixture of 519.0 g of 99 percent pure m-cresol, 538.2 g of 97 percent pure 2,6-bis-(hydroxymethyl)-p-cresol and 20 g oxalic acid dihydrate in a solvent mixture of 40 ml deionized water and 200 ml ethyl cellosolve acetate. The reaction mixture was heated to about 70° C. to initiate the reaction forming the copolymer block segments. At 102° C., 32.6 g of 36.9 percent formaldehyde was added in 8 minutes to the reaction mixture to form substantially m-cresol formaldehyde block segments and to chemically bond these segments to the previously formed copolymer blocks. After heating the mixture at reflux for three hours, the amount of heat was increased to remove the water and solvent by distillation. When the temperature of the reaction mixture reached about 220° C., a partial vacuum was applied and was gradually increased to 4 mm Hg to remove the unreacted monomers. Maximum mixture temperature during vacuum stripping was about 226° C. The copolymer was poured from the reaction kettle and allowed to cool. About 840 g of product having a Tg of 112° C. was obtained. was formed in a solvent mixture of 40 ml forming the copolymer block segments

Procedure: Hexachlorobenzene (35 g) was slurried in 160 ml of anhydrous ethyl ether at −40° C. A 2.5 M hexanes solution of n-butyllithium (54.1 mL) was added, and the reaction was stirred for 30 minutes at −40° C. Perfluoro-2-ethoxyacetylfluoride (40 g, 72% pure, prepared from 2-ethoxyethyl acetate by the method described in Example 1 of U.S. Pat. No. 5,326,919, incorporated herein by reference) was added to the −40° C. reaction mixture which was then allowed to warm slowly to room temperature. The reaction mixture was quenched with 200 mL of cold 5% aqueous HCl. The aqueous mixture was extracted with ethyl ether and the extracts were dried over MgSO4 and rotary evaporated to give pentachlorophenyl perfluoroethoxymethyl ketone (49% crude yield). Vacuum distillation (105-109° C., 240 Pa) using a 15 cm Vigreux column gave 19.7 g of a colorless liquid which slowly crystallized on standing. 5,326,919, incorporated herein by reference) was added to the −40° C. reaction mixture which to warm slowly to room temperature The reaction mixture was quenched with 200 mL of cold 5% aqueous HCl The aqueous mixture was extracted with ethyl ether the extracts were dried over MgSO4 rotary evaporated

Procedure: The 2-liter flask charged with 600 g of ethylene glycol monoethyl ether acetate was heated until the internal temperature of the flask became 80° C. Then, 2.30 g (0.01 mol) of polymerization initiator V-601 was added thereto and agitated for five minutes. Subsequently, the above monomer mixture solution was dropped into this solution over a period of six hours. After the completion of the dropping, the mixture was further heated and agitated for two hours. Thereafter, the reaction liquid was cooled to room temperature. After the cooling, the reaction liquid was dropped into three liters of hexane, thereby precipitating a polymer. The polymer solid was collected by filtration and dissolved in 500 g of acetone. This solution was dropped once more into three liters of hexane, and the thus obtained solid was collected by filtration and dried in vacuum. Thus, 151 g of poly(4-acetoxystyrene/t-butyl methacrylate/benzyl methacrylate) was obtained. was heated until the internal temperature of the flask became 80° C was added Subsequently, the above monomer mixture solution was dropped into this solution over a period of six hours After the completion of the dropping, the mixture was further heated agitated for two hours Thereafter, the reaction liquid After the cooling, the reaction liquid precipitating a polymer The polymer solid was collected by filtration dissolved in 500 g of acetone This solution was dropped once more into three liters of hexane the thus obtained solid was collected by filtration dried in vacuum
