The MA–OC-1–VB terpolymer was synthesized via radical terpolymerization method.
The CdS nanocrystals were synthesized within MA–OC-1–VB terpolymer.
The terpolymer/CdS nanocomposite is more thermostable than the terpolymer itself.
The UV–vis shows shifting to higher energies which is appropriate for nanocrystals.
