Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 693-67-4, is researched, SMILESS is CCCCCCCCCCCBr, Molecular C11H23BrJournal, Article, Macromolecules (Washington, DC, United States) called 4-Carboalkoxylated Polyvalerolactones from Malic Acid: Tough and Degradable Polyesters, Author is Fahnhorst, Grant W.; De Hoe, Guilhem X.; Hillmyer, Marc A.; Hoye, Thomas R., the main research direction is carboalkoxylated polyvalerolactone malate tough degradable polyester.HPLC of Formula: 693-67-4.
Eight 4-carboalkoxyvalerolactones (CRVLs), varying in the composition of their alkyl (R) side chains, were synthesized from malic acid and subjected to ring-opening transesterification polymerization (ROTEP) using di-Ph phosphate [DPP, (PhO)2PO2H] as a catalyst. Each CRVL produced a semicrystalline poly(4-carboalkoxyvalerolactone) (PCRVL), and the nature of the R group impacted the thermal transitions of these polyesters. Bulk polymerizations at 70°C allowed for preparation of high molar mass samples that contained small amounts of branching, as evidenced by 1H NMR spectroscopy, MALDI spectrometry, size-exclusion chromatog., and eliminative degradation Tensile testing of these lightly branched, high molar mass samples revealed that these polyesters are tough (tensile toughness values up to 88 ± 33 MJ•m-3) and have Young’s moduli (E) up to 186 ± 13 MPa. The acid- and base-catalyzed hydrolytic degradation of the PCRVLs was quant. monitored using total organic carbon anal., and effect of the alkyl chain length on PCRVL hydrolysis rate was determined Finally, the Me ester variant of these malic acid-derived thermoplastics is known to be chem. recyclable.
