CATALYZING GREEN CHEMISTRY
Key characteris3cs of CO2-­‐based polyols •  100% polycarbonate backbone: perfectly alternating CO2 / epoxide units
yielding 100% carbonate and zero ether linkages
•  Precise control of molecular weight: any Mw from ~500 g/mol to 10,000+
g/mol, all with polydispersity indexes (PDIs) of <1.2
•  Linear or branched: linear 2-functional diols or branched structures can be
created (demonstrated up to 6-fn to date)
•  Perfect -OH functionality: diols are 2.0 functional with zero unsaturation;
hydroxyls can be primary or secondary depending on epoxide used
•  No Color: “Water white” polyols create transparent PU products

Understanding the Structure-­‐Property Rela3onship of PPC Polyols in Urethanes Novomer has a highly unique polyol technology… Exis3ng Polyol Technology Intui3on on how Novomer might compare Polyethers (PPG, PTMEG) •  Lack of ethers = beAer UV resistance? Polyesters (adipates, etc.) •  Lack of esters = beAer hydroly0c stability? Exis3ng Polycarbonates •  Higher density of carbonate linkages = even higher strength? © 2013 Novomer Inc.
...Thus we looked at its performance in PUs in a two-­‐phase approach 1 Study linear PUs changing only polyol (i.e., sob) segment •  PPC vs. exis0ng PCD and ester control polyols •  Same hard segment concentra0on 2 Study how adding PPC impacts exis3ng formula3ons •  Studied both ester-­‐based elastomers and ether-­‐based foams •  Look for impact of PPC 12
