Poly(lauryl methacrylate) is used as an additive in motor oils to counter the loss of viscosity at high temperature. The structure is
The long hydrocarbon chain of poly(lauryl methacrylate) makes the polymer soluble in oil (a mixture of hydrocarbons with mostly 12 or more carbon atoms). At low temperatures the polymer is coiled into balls. At higher temperatures the balls uncoil and the polymer exists as long chains. Explain how this helps control the viscosity of oil.
Answer to relevant QuestionsEthelene oxide, is an important industrial chemical. Although most ethers are unreactive, ethylene oxide is quite reactive. It resembles C2H4 in its reactions in that many addition reactions occur across the C—O bond. a. ...Consider the following five compounds. a. CH3CH2CH2CH2CH3 b. c. CH3CH2CH2CH2CH2CH3 d. e. The boiling points of these five compounds are 9.5°C, 36°C, 69°C, 76°C, and 117°C. Which compound boils at 36°C? Explain. The structure of tartaric acid is a.
