Styrenated Oil Synthesis with Cyclic Carbonate Functional Groups on Polystyrene Segment

Area of Science:

• Polymer Chemistry
• Materials Science

Background:

• Developing novel copolymers with tailored properties is crucial for advanced material applications.
• Oil-based macroinitiators offer a sustainable route for polymer synthesis.

Purpose of the Study:

• To synthesize and characterize an oil-modified copolymer of 4-[(prop-2-en-1-yloxy)methyl]-1,3-dioxolan-2-one (AGC) with styrene.
• To functionalize the copolymer with (3-aminopropyl) triethoxysilane (APTES) and investigate its crosslinking behavior.

Main Methods:

• Synthesis of an oil-based macroinitiator (OBMI) from linseed oil partial glycerides and 4,4-azobis-4-cyanopentanoyl chloride (ACPC).
• Copolymerization of OBMI with AGC and styrene to form OBMI-St-AGC.
• Silane functionalization of OBMI-St-AGC with APTES.
• Characterization using FTIR, 1H NMR, TGA, and DSC.
• Crosslinking of the silane-functionalized copolymer via the sol-gel process.

Main Results:

• Successful synthesis of the oil-modified copolymer OBMI-St-AGC.
• Effective silane functionalization yielding OBMI-St-AGC-APTES.
• Confirmation of the copolymer structure and properties through spectroscopic and thermal analyses.
• Demonstration of crosslinking capability via the sol-gel process.

Conclusions:

• The study successfully synthesized and characterized a novel oil-modified, silane-functionalized copolymer.
• The developed copolymer exhibits crosslinking potential through the sol-gel process.
• This research contributes to the development of new functional polymers derived from renewable resources.
