Area of Science:

• Polymer Chemistry
• Materials Science

Background:

• Polyunsaturated poly(ether carbonate)s offer versatile functional groups for material synthesis.
• Multicomponent polymerization provides routes to complex polymer architectures.

Purpose of the Study:

• To synthesize novel polyunsaturated poly(ether carbonate)s.
• To investigate their cross-linking behavior for transparent film formation.
• To explore their potential in coating applications.

Main Methods:

• Multicomponent polymerization of CO2, propylene oxide, maleic anhydride, and allyl glycidyl ether.
• Sequential and simultaneous monomer addition to control polymer architecture (ABXBA multiblock and AXA triblock).
• UV- or redox-initiated free-radical curing of the synthesized polymers.

Main Results:

• Successfully synthesized poly(ether carbonate)s with ABXBA multiblock and AXA triblock structures.
• Polymers possess diverse functional groups, including terminal hydroxyl, maleate, and pendant allyl groups.
• Facile UV- or redox-initiated free-radical curing was achieved due to the unique double bond substitution.
• Resulting cross-linked materials are transparent.

Conclusions:

• The developed polyunsaturated poly(ether carbonate)s are suitable for creating transparent films.
• The versatile functional groups and facile curing enable tailored material properties.
• These materials show significant potential for various coating applications.
