The polymers consist of chains, each chain contains C-H or related groups bound together by strong sigma bonds, which provide strength and integrity to the polymer. Inter-chain coupling is small. Therefore the materials are quasi-one dimensional (quasi-ID). The structure allows the dopant atoms or molecules to go in space in-between the chains. 

The strength of polymer-polymer interaction is represented here by a new parameter A instead of the usual x The "polymer-polymer inter-...

Cationic polymerization of sulfides, as described above, proceeds with extensive chain transfer to polymer (inter- or intramolecularly). Thus, it can not be considered as a competitive synthetic method in comparison with anionic polymerizations, addition of dithiols to a,o)-diolefins or condensation of dithiols with a,(a-dihalides.

D compounds could also be of interest for the design of optical devices. Indeed, in coordination polymers, inter-lanthanide distances can be controlled. This allows the synthesis of compounds with a high content in lanthanide ions. Furthermore the chemical likeness of the lanthanide ions allows the synthesis of hetero di-lanthanide compounds with a veiy good random distribution of the two rare earths. This property could be used for diluting the optically active lanthanide in a given ftamewoik or for enhancing optical properties thanks to up-conversion phenomena for instance.

Molecular Weight - The molecular weight and molecular weight distribution strongly affect the solution properties of specialty polymers and their applications. Hydrophile to Lipophile Balance (HLB) the type and content of hydrophiles and lipophiles significantly impacts specialty polymers inter- and intra-molecular associations. 

The properties of mbber blend composites are determined by the particle size, surface stmctme, and surface activity of filler. If the size of filler particles greatly exceeds the polymer inter-chain distance, it introduces an area of localized stress. This can contribute to elastomer chain rupture on flexing or stretching.
