With the aim to improve the compatibility of polycarbonate (PC)/polypropylene (PP) blends, a novel aromatic polycarbonate diol (PCDL) was synthesized by the transesterification reaction, then a series of polycarbonate-based thermoplastic polyurethane elastomers compatibilizers (TPU-Gx) with octadecyl side chains were successfully prepared by introducing different content of PCDL and glyceryl monostearate (2,3-Dihydroxypropyl octadecenoate; GMS). The structures of synthesized products were confirmed by Fourier transform IR spectroscopy and NMR hydrogen spectroscopy. Thermogravimetry results showed that all TPU-Gx had good thermal stability. The effects of TPU-Gx on the compatibilization of PC/PP blends were investigated in the aspect of morphol., mech., thermal, and rheol. properties. The results showed that all TPU-Gx could enhance the interfacial adhesion between PC/PP and improve the mech. properties of PC/PP blends. Among them, the addition of TPU-G1.5 containing 6.0 wt% PCDL and 1.5 wt% GMS made PC/PP/TPU-G1.5 blends show the highest impact strength, which increased by 54.1% when compared with that of pure PC/PP blends. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Related Products of 102-09-0).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Magnesium-catalyzed hydroboration of organic carbonates, carbon dioxide and esters was written by Cao, Xu;Wang, Weifan;Lu, Kai;Yao, Weiwei;Xue, Fei;Ma, Mengtao. And the article was included in Dalton Transactions in 2020.Category: esters-buliding-blocks The following contents are mentioned in the article:

A low-valent Mg(II) complex [(^XylNacnac)Mg]₂ was employed as a highly efficient precatalyst for the hydroboration of a variety of cyclic and linear organic carbonates, polycarbonates, CO₂ and esters with HBpin under mild conditions. The resultant boronates can be used for the preparation of the corresponding value-added diols, triols or alcs. through hydrolysis. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Category: esters-buliding-blocks).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Category: esters-buliding-blocks

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.SDS of cas: 102-09-0

Historical stages of development of this technol. and the main technol. solutions ensuring its effectiveness were reviewed. The advantages of the phosgene-free technol. were demonstrated using the example of Kazanorgsintez PJSC. The main characteristics of the polycarbonates are presented. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0COA of Formula: C13H10O3).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.COA of Formula: C13H10O3

Substituted vinylene carbonates were directly prepared from aromatic aldehydes following a one-pot Benzoin condensation/transcarbonation sequence under solvent-free conditions. The combination of a N-Ph substituted triazolium salt NHC precursor and 4-dimethylaminopyridine (DMAP) was found essential to reach high yield and selectivity. The reaction scope was investigated with a range of aromatic aldehydes and the corresponding vinylene carbonates were obtained with 32-86% isolated yields (14 examples). This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Product Details of 102-09-0).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Product Details of 102-09-0
