Session L36 - General Poster Session II.
POSTER session, Wednesday morning, March 22
Exhibit Hall, MCC
We study rheologiacl behavior of di-end-functionalized polymer confined between two flat walls by using Monte Carlo simulation. In order to investigate the effect of the associating structure induced by functional groups on the rheological properties, we simulate three kind of telechelic chains with different number of associating capacity, f=1, 2 and 3 and compared the shear responses of these polymers. When the associating capacity of a functional group is larger than 1, physically crosslinked network of associating structure effectively blocks the extreme chain stretching against shear deformation, resulting in decrease of limiting shear stress.
