Why are side chain lengths different by 4 like hexyldecyl(HD), octyldodecyl(OD). Why don't we use symmetric side chain?

why are all side chain lengths different by 4 like hexyldecyl(HD), octyldodecyl(OD), decyltetradecyl(DT). Why don't we use symmetric side chain?

I appreciate any references that show the different properties of between the polymers with symmetric/asymmetric side chains.

Alkyl chain length whether short or long have its effect on the movement of parent chain in the polymeric molecules bringing in more of less rigidity and showcase tacticity. Given this phenomenon it will show variation in properties with shorter or longer side chains.
