Topological polymer may refer to a polymeric molecule that possesses unique spatial feature, such as linear, branched, or cyclic architectures. Or it could refer to polymer networks that exhibit distinct topologies owing to special crosslinkers. When self-assembling in a certain way, polymeric species with simple topological identity could also demonstrate complicated topological structures in a larger spatial scale via different topological crosslinking.

Definition
·        The broad definition topological polymer, including the topology in a single polymer chain or the topology in a polymeric network.

·        The feature of topological polymer, the broader interest.

·        Mention the structure-property relationships and draw a big picture.

·        Brief introduction of real examples of topological polymer and polymer network topology.

Topological polymer classification
·        Flory was the earliest one who came up with polymer network topology and its importance and some theories were successfully developed afterwards.

·        For a single molecular chain, the topology was firstly systematically described by Tezuka and coworkers.

·        Based on different spatial feature, a single polymer chain be catalogued into a few classifications, including linear, branched and cyclic.

·        Table would attach a table summarizing common polymer topology, including topology notation, topology schematics and so on.

Linear
The simplest variation of polymer topology but could derive a more complex topological structure in a larger scale by forming a polymer network.

Branched
·        Constitutional isomers of linear topology

·        H shape, comb shape, star shape and dendrimers

Cyclic
Forming a cyclic structure would lead to a higher unsaturated degree but would form a more complicated topology by catenating or interpenetrating.

Monocyclic
Topology with only one cycle in the polymer chain.

Bicyclic

Two cycles are present in the polymer network by catenating or linking by a linear polymer chain.

Polycyclic

Multiple cycles are present in a single polymer chain, either linked by a linear polymer chain or catenating with each other to form a holistic molecule.

Polymer network topology
·        Simple linear polymer chain, when crosslinked by a complicated polymer crosslinker (physical or chemical crosslinker), would result in a complicated polymer network.

·        Figures with redesigned topological schematics would be illustrated here.

Branched crosslinking
·        Crosslinker with multivalency can derive more complex network.

·        Branched functionality

Cyclic crosslinking
·        Cyclic polymer crosslinking network.

·        Rotaxane-based crosslinking network.

·        Catenane-based crosslinking netwok.

Topological polymer single chain
·       Ref 2 would be the main source for the synthesis of topological polymer single chain.

Topological polymer network
·       Ref 5 would be the main source for the synthesis of topological polymer network.
