摘要：

Polyisoprene (PI) stars (arm number f = 4 similar to 237) were prepared by coupling of PI monoanions with tetrachlorosilane or by cross-linking PI anions with divinylbenzene. The structural ordering of such stars was investigated through small-angle X-ray scattering, PI stars (f > ca. 90) formed a body-centered cubic (bcc) structure near the overlap threshold. This structure changed to a mixed lattice of bcc and face-centered cubic structures with increasing polymer concentration. (C) 1997 Academic Press.
