NOVOMER
CATALYZING GREEN CHEMISTRY
Novomer’s CO2-based Polymers
 Aliphatic polycarbonates: Reaction of CO2 with
epoxides like PO and EO.
 Alternating CO2/epoxide linkages with direct
incorporation of CO2 into polymer chain.
 Molecular Weight (Mw) control possible:
 > 40,000 Da: Thermoplastics
 1,000 – 10,000 Da: Polyols
 Exploring film extrusion, thermoforming,
injection and blow molding of high Mw PPC
and/or its blends with other polymers.
 Exploring use of polyols for can/coil coating,
composites, and foam applications.

Permeability – PPC Blends
50/50 PPC/LLDPE Blend
50/50 PPC/HDPE Blend
Sectioned perpendicular to extrusion direction in both cases.
• Good dispersion of dispersed phase in blends.
• Co-continuous morphology seen with LLDPE explains higher barrier enhancement.

CO2 is permanently converted and sequestered into the plastic
The CO2 is being used in place of fossil fuels
The PPC reaction occurs using lower energy than most polymerization reactions.
Novomer’s carbon footprint is 40-70% lower than competing materials.

Where Next?
High Mw Thermoplastic Opportunities
Plastic Packaging
A. Near term
• Films (Monolayer and Multi-layer laminates)
• Extrusion Coatings on Paperboard
• Blends with thermoplastic starch & polyolefins
B. Mid term - Rigid Packaging Applications (Blends)
Novomer’s synthetic chemistry allows functionalization and Mw control
to achieve desired performance properties.
