NOVOMER C ATALYZING G REEN C HEMISTRY 10 © 2010 Novomer Inc. CONFIDENTIAL O 2 and WV Permeability PPC – Polyolefin Blends An unexpected result with LLDPE Barrier Enhancement Factor for 50/50 Blends Actual Additivity Model LLDPE/PPC HDPE / PPC 1.7 PP/PPC Additive model: P blend =  1 P 1 +  2 P 2 O 2 permeability reduction exceeds that expected based on an additive model for 50/50 blends.

NOVOMER C ATALYZING G REEN C HEMISTRY 11 © 2010 Novomer Inc. CONFIDENTIAL Permeability – PPC Blends Good dispersion of dispersed phase in blends. Co-continuous morphology seen with LLDPE explains higher barrier enhancement. 50/50 PPC/LLDPE Blend Sectioned perpendicular to extrusion direction in both cases. 50/50 PPC/HDPE Blend

NOVOMER C ATALYZING G REEN C HEMISTRY 12 © 2010 Novomer Inc. CONFIDENTIAL Carbon Balance CO 2 is permanently converted and sequestered into the plastic The CO 2 is being used in place of fossil fuels The PPC reaction occurs using lower energy than most polymerization reactions. PS PVC PE PP Propylene CO 2 Processing Novomer Oxide PPC Source: Industry Data from European Plastics Association Novomer’s carbon footprint is 40-70% lower than competing materials.
