Popis: | Random copoly(p-phenylene sulfide sulfone/ketone)s (PPSS/K) [PhSO 2 PhS] m [PhCOPhS] n are prepared in high yield by the polycondensation of sodium hydrosulfide (NaSH) with bis (4-chlorophenyl) sulfone (BCPS) and 4,4'-dichlorobenzophenone (DCBP). The copolymers with sulfone/ketone mole ratios (S:K)> 25:75 are amorphous, while the copolymers with S:K ratios ≤ 25:75 are crystalline. These materials form tough, creaseable films and exhibit a linear increase in the T g with increasing sulfone content |
