Polycarbonate diols to produce elastic polyurethane foams - a method of immobilization of carbon dioxide into a polymer structure

Title:
Polycarbonate diols to produce elastic polyurethane foams - a method of immobilization of carbon dioxide into a polymer structure
Abstract:
Using carbon dioxide as feedstock for polymers is a big challenge and a chance for our sustainable future. It has an immense potential for the coming decade, which comes much faster than expected. Scientists are very active lately in carbon dioxide chemistry research, especially in the field of carbon dioxide based chemicals and polymers. We report here on the stability of higher molecular weight polycarbonate diols and the formation of specialty poly-urethanes such as UV stable elastomers, semi-rigid foams, and elastic sealants. These polyurethanes are produced from polycarbonate diols (ETERNACOLL®) and aromatic 4,4’-diphenyl-methane diisocyanate, from aliphatic hexane-1,6-diisocyanate, or the trimer, diisocyanates. We use butane-1,4-diol or pentane-1,5-diol as a chain extender. The thermal and mechanical properties of the polyurethanes obtained are determined by differential scanning calorimetry (DSC) anddynamic mechanical analysis (DMA). The data obtained show no phase segregation or any type of crystallinity.Any possible changes in the molecular mass distribution of the samples are investigated with the application of gel permeation chroma-tography (GPC).It is evidencedthat only heat treatmentbrings about molecular mass distribution shifts to lower values.Keywords: polycarbonate polyols, synthesis, polyurethanes, foams
