Polar side groups (such as -Cl) give... 10 of 20 pack together more closely than branched chains, so are stronger. Straight, unbranched chains can... 11 of 20 Stereoregularity in polymers Polymers can be packed together more closely is side groups are orientated in a regular way. 12 of 20 very flexible Hydrocarbon chains are... 13 of 20 covalent bonds to make it harder to break them apart.
