Polymer chains have different abilities to rotate into many conformations depending on steric hindrance along the chain (side groups, e.g. backbone chemistry) & free volume in the polymer based on temperature, etc. Polystyrene (spelling corrected) has an aromatic ring on every other carbon of the backbone. Thus it cannot acquire many conformations & is considered stiff. Put another way, this lack of flexibility imparts the property of being brittle.
