In the past few decades, considerable attention has been paid to the thermoplastic elastomer (TPE). Among them, hydrogenated styrenic block copolymers (HSBCs) have attracted extensive interest because of outstanding ozone resistance, remarkable aging properties, and environmental friendliness. Therefore, theor. and exptl. investigations on the HSBCs/PP/oil composites have been reported many times, but the influence of mol. structure on the structure and properties of composites has yet to be identified. In this study, three HSBCs with different mol. structures were used as the research object to systematically study the effects of their mol. structural differences on the aggregate structure, microstructural, mech., and thermal properties of HSBCs/PP/oil composites. It was found thatthe content of side groups in the mol. chain was the main factor affecting the structure and performance of the HSBCs/PP/oil composites. This research can provide theor. guidance for the mol. design and structural control of the new HSBC, so it has obvious theor. significance and practical value. 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: 6683-19-8Recommanded Product: 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)).
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 are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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.
