As the topological structure of macromolecular chains is very important to the properties of the materials
the relationship between the topological structure of polymer chains and the properties of materials has always been an important topic in the field of polymer materials. Living/controlled polymerization provides a variety of methods for the controlled synthesis of comb-like polymers
through which the topological structure of comb-like polymers can be easily regulated. Currently
there are three main synthesis strategies adopted
namely "Graft onto" strategy
"Graft through "strategy and "Graft from" strategy. Combined with author's research work
this paper summarizes the progress in the polyolefin and polystyrene based comb-like (co)polymers
including the synthesis of comb-like polymers with well-defined structure
and the relationship between chain topological structure and performance of the controllable synthesis of comblike (co)polymers
which focus on the effect of long chain branched structure parameters (branched chain length
density and chemical composition of branch chain) on melt behavior
foaming behavior and crystallization behavior of comb-like (co)polymers.
