Ultra-high mol. weight polyethylene (UHMWPE) and linear low-d. polyethylene (LLDPE) with different ratios were melt-blended in an internal mixer. Results of rheol. tests and SEM indicate that the blends are well miscible in the range of small addition amount of UHMWPE. The content of UHMWPE is suggested to be less than 5.0 wt%, to guarantee good compatibility of biphasic blends. Differential scanning calorimetry studies indicate that co-crystallization occurs between UHMWPE and LLDPE. The crystallinity increases with the increase of UHMWPE as a nucleating agent. As a result, an improvement in mech. properties is achieved. When the addition amount of UHMWPE is 5.0 wt%, the impact strength, breaking elongation, Young’s modulus, and tensile strength are significantly increased by 27%, 25%, 75%, and 21% resp. 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: 6683-19-8Application of 6683-19-8).
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. 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.Application of 6683-19-8
