Polymer functional group
WebMar 28, 2024 · Polymers containing cyclic derivatives are a new class of macromolecular topologies with unique properties. Herein, we report the synthesis of a triblock copolymer containing a spirocyclic mid-block. To achieve this, a spirocyclic polystyrene (cPS) mid-block was first synthesized by atom transfer radical polymerization (ATRP) using a tetra … WebIn the case of polymers, the functional groups are generally attached to the nonpolar core of the carbon atoms in each repeating unit of the corresponding polymer, infusing the carbon chain with specific chemical characteristics. Some functional groups have an ionic charge on them, as observed in carboxylate salts containing the -COO – ionic ...
