R. Thomann et al., VAPOR INDUCED CRYSTALLIZATION OF SYNDIOTACTIC RANDOM COPOLYMERS OF STYRENE WITH P-N-BUTYLSTYRENE, Polymer bulletin, 40(2-3), 1998, pp. 313-319
The vapor induced modification of bulk samples of syndiotactic random
copolymers of styrene and p-n-butylstyrene is studied by wide-angle X-
ray scattering and light microscopy. Two samples with p-n-butylstyrene
contents of 4 and 11 mol% are compared. It is shown that treatment wi
th CHCl3 leads to the formation of a clathrate modification similar to
that of neat syndiotactic polystyrene. The change of the surface topo
graphy of the copolymers as a result of CHCl3 vapor exposition is stud
ied by tapping-mode/height-mode atomic force microscopy.
