Which of the statement/s below is/are inaccurate? a. Crosslinked polymers are stronger and have lower elongation at break than branched and network polymers O b. 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 O d.
