2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8) 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. 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.Related Products of 6683-19-8

Effect of polypropylene molecular weight distribution on the balance between the toughness and rigidity of the impact polypropylene composites was written by Li, Fushi;Gao, Yunbao;Yan, Nan;Zhang, Chunyu;Zhang, Xuequan;Jiang, Wei. And the article was included in Journal of Applied Polymer Science in 2022.Related Products of 6683-19-8 This article mentions the following:

In this study, homo-polypropylene (HPP) with the same number average mol. weight (M n) while different mol. weight distribution (MWD) are directly melt blended with a polyolefin elastomer (POE) in order to study the effects of the MWD of HPP on the brittle-ductile transition (BDT) and the balance between toughness and rigidity of the PP/POE composites. The results show that for the same number average mol. weight HPP, the wider the MWD, the higher the brittle strength σb of the HPP is, and the larger the critical interparticle distance (IDc) of the composite is. Larger IDc means lower modifier content can induce the BDT, and thereby leads to less modulus loss of the composites. Namely, the toughened HPP with wider MWD can have a better balance between toughness and rigidity. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Related Products of 6683-19-8).
