Abstract:
Phosphorus-containing polymers have found wide application. Consequently, their synthesis is of great interest. Existing methods, however, primarily afford polyphosphonates and polyphosphates. Herein, we report a step-growth ″phosphoryl-ene″ polymerization strategy for incorporating phosphinate directly into the polymer backbone. Readily accessible AB-type phosphoryl monomers undergo radical step-growth polyaddition to yield the target polyphosphinates. Furthermore, AA-type bis-phosphoryl monomers can be used in radical step-growth polymerization with dienes or anionic step-growth polymerization with di-esters. This strategy provides an unprecedented and versatile approach to phosphorus-containing polymers, opening promising possibilities for polyphosphinate-based functional materials.

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.

Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
