Pendant groups have large effect on chain mobility. The adamantine group acts as a “fish hook” which catches on to any nearby molecule and reduces chain mobility. The magnitude of this effect is related to the size of the pendant functional group-large groups (eg. Adamantane) greatly reduce chain and polymer mobility.
