Molecular Weight of Step-Growth Polymers

2.5K
Step growth polymerization involves bi or multifunctional monomers. Bifunctional monomers react to form linear step growth polymers, whereas multifunctional monomers react to form non-linear or branched 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.
The extent of the...

Main Methods:

  • Synthesis of SMP foams incorporating ether-containing monomers.
  • Characterization of physical, thermal, and shape memory properties.
  • In vitro degradation studies in oxidative and hydrolytic media.
  • Assessment of cytocompatibility and blood interactions.

Main Results:

  • Achieved tunable degradation rates with up to 15% mass remaining after 108 days.
  • Demonstrated controlled erosion profiles in tested degradation media.
  • Confirmed cytocompatibility and favorable blood interactions of the synthesized foams.

Conclusions:

  • The developed SMP foams offer adjustable degradation kinetics for extended in-body use.
  • These foams exhibit desirable properties for applications requiring long-term stability.
