Geometrical isomers include syndiotactic, atactic and isotactic types and only differ by their spatial repetition of side group positions. O c. Elastomers typically have higher elongation at break values than brittle and plastic polymers and they don't experience necking which plastic polymers do experience Od. The presence of bulky side groups and double bonds decreases the freedom of the polymer chain to rotate and change it's spatial configuration O e.
