THE SYNTHESIS AND CHARACTERIZATION OF BLOCK COPOLYMERS

Segmented (AB) $\sb{n}$ polyurethanes. A series of polyether-polyurethane (PEPU) were synthesized and characterized. Soft segments were poly(propylene oxide) (PPO; M$\sb{\rm n}$ = 2,000) or poly(tetrahydrofuran) (PTHF; M$\sb{\rm n}$ = 1,650). Hard segments were formed from 4,4$\sp\prime$-diphenylmet...
