WebDec 1, 2024 · Bio-based polycarbonate from limonene oxide and CO2 with high molecular weight, excellent thermal resistance, hardness and transparency Article Full-text available The valorization of the platform polymer PLimC is illustrated in Fig. 2. When butyl-3-mercaptopropionate (B3MP) is used, an enormous change in mechanical properties is achieved. This leads to a transformation of the high-Tg thermoplastic into rubbery PLimC-B3MP with a nearly three orders of magnitude decreased … See more The enormous versatility of PLimC is reflected in an experiment, where the thiol-functionalized ester B3MP—the pure ester is found in many fruits30—is clicked to the double bond in nearly quantitative yield (schematic in Fig. 3 … See more In a recent publication we stated the thermal properties of PLimC, that is, a Tg of 130 °C and a 5% decomposition temperature (T5%) of 240 °C, resulting in a rather narrow … See more Apart from the functionalization of PLimC, of course, it is also possible to hydrogenate the double bond, to render it unreactive, when it is heat processed or stored for a prolonged period of time. In contrast to the … See more The idea to render PLimC more hydrophilic was born, when studies on the degradation behaviour of pure PLimC in highly active compost at 60 °C (positive reference poly(L-lactic acid) disintegrated within 1 week) had … See more high schools in fitchburg
