FLOW IMPROVERS AND CLOUD POINT DEPRESSANTS |
摘要 |
Additives suitable for improving the flow and/or depressing the cloud point of crude oils, lubricating oils and especially fuel oils are polymers containing defined alkyl groups of at least 8 carbon atoms chain length. Such polymers are either (a) of a mixture of monomers having only two alkyl groups one being at least 3 carbon atoms longer than the other or (b) of a mixture of monomers having only three alkyl groups each differing by at least 3 carbon atoms and the middle alkyl group being half the combined length of the other two. Alternatively, the polymer may be derived from a monomer having the two defined alkyl groups (a) or the three defined alkyl groups (b). |
