the first reason i gave above
the second reason :
monomers of addition polymers can only have a DOUBLE BOUND >c=c<
monomers of condesation polyemers can be made of 2 differnet monomers and can have >c=c< sometimes

Wait, im sorry, Helium and Nizzz ----> u need to know that as you go down the fractions, (i) the no. of carbon atoms increases, (ii)) it gets less flammable and (iii) its boiling point and melting point increases.
