Ladder polymer

In a typical one-dimensional polymer, e.g. polyethylene and polysiloxanes, the monomers form two bonds, giving a chain.

[1] According to one definition, a ladder polymer, adjacent rings have two or more atoms in common.

[2] Organic ladder polymers are of interest because they can exhibit exceptional thermal stabilities and the conformation of the subunits is constrained.

[5] Its backbone is composed of aromatic rings and the ladder structures enable the uninterrupted polymer chains with periodic linkages.

[7] BBL's glass transition temperature (Tg) is estimated to be around 500 C based on differential scanning calorimetry (DSC) measurements.
