WebFeb 6, 2012 · I'm not really sure how to calculate this since terephthalic acid isn't a reactant itself and is just mostly present in the form of a copolymer. PET reacted = 2.482g or 0.01291605 mol. Mass of the copolymer unit = 192.164 g/mol. Mass of terephthalic acid = 166.128 g/mol. Mass of ethylene glycol = 62.068 g/mol. Web95 rows · Also, it is equally interesting to understand the main difference between Tensile Strength and Yield Strength. Yield Strength is the stress a material can withstand without … can momentum be created

Enolate reacts with alkyl halides or carnonyl compounds to yield the product of a new C-C bond. WebHigh char-yield phenolic resin can be obtained as the heating rate is lower than 20·C/hr, • The highest char yield obtained for NaEC0 3 or NaOH catalyzed phenolic resin is 71%, Ca(OH)E-catalyzed phenolic resin is 69.5% , and NH 40H-catalyzed phenolic resin is 64.0% respectively. Although the char yield obtained from NaOH, NaEC0 3 or ca(OH) E Web(For this calculation "n" is the number of bonds of length "l", so for a vinyl polymer "n" is twice the degree of polymerization and "l" is 1.54Å for a C-C bond.) The characteristic ratio is the conventional measure of short-range interactions, although, direct measurement of ... which yields, b* = b θ /nθ 1/4 ... fix friendship
