A copolyester, comprising structural units represented by [I], [II], [III] and [IV]. The number of structural units represented by [III] is 1-99% of the number of structural units represented by [I], and the number of structural units represented by [IV] is 0-99% of the number of structural units represented by [I]. Also provided are a preparation method therefor and an application thereof. Because an introduced high-temperature self-crosslinking group and an ion group can improve the melt viscosity and the melt intensity during burning of a copolyester, and effectively enhance the char-forming capability of the copolyester, the copolyester exhibits excellent flame retardance and anti-dripping performance. The preparation process for the copolyester is mature, convenient to operate, and easy to control and apply to industrial production.

Radical cascade reactions enabling sequence-controlled ring-closing polymerization and ring-opening polymerization for the controlled synthesis of polymers with complex main-chain structures are provided. Facile syntheses leading to low-strain macrocyclic monomers consisting of the ring-opening triggers and extended main-chain structures are also provided. The present disclosure further provides methods for excellent control over polymer molecular weights and molecular weight distributions and high chain-end fidelity allows for the preparation of polymeric systems with well-defined architectures. Further provided are the general nature of the radical cascade-triggered transformations in polymer chemistry, and its application to the synthesis of polymers with diverse main-chain structural motifs with tailored functions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

In various embodiments, the present invention relates to a series of anti-fouling zwitterionic biodegradable thiol-yne elastomers that incorporate degradable C.sub.4-C.sub.14 dicarboxylic acid-based monomer units made using a nucleophilic thiol-yne polymerization methodology that targets high cis-content at comparable molar masses to provide excellent mechanical properties and zwitterionic side chains that provide anti fouling properties. As each C.sub.4-C.sub.14 dicarboxylic acid-based monomer unit contains at least two labile ester linkages, altering the stoichiometry of degradable C.sub.4-C.sub.14 dicarboxylic acid-based monomer unit incorporation allows the degradation rate of the material to be tuned precisely, while retaining control over the mechanical properties by maintaining the cis/trans stereochemistry of the double bonds to provide independent tuning of mechanical and degradative properties.
