Description

ポリメタクリレート（ＰＭＡ）系の粘度指数向上剤は、Ｍｗが３０，０００以上８００，０００以下であれば、式（１）に例として示すような非分散型でも、式（２）に例として示すような分散型でも良く、特に制限されることなく選択される。また窒素化合物やポリアルキレングリコールエステルなどの極性モノマーを含むものでも、炭化水素以外の元素成分を含むものでも良い。また、構造の一部がポリメタクリレート以外の高分子化合物であっても、ポリメタクリレート部を持つ共重合体、例えば原料としてエチレン、プロピレン、ブチレン等の１種以上を用いて共重合したポリメタクリレート−オレフィンコポリマー共重合体、ポリメタクリレート-ポリスチレン共重合体等も使用することができる。ポリメタクリレート系の粘度指数向上剤を使用することで、良好な低温粘度特性を得ることができる。 The polymethacrylate (PMA) -based viscosity index improver is shown as an example in the formula (2) even if it is a non- dispersion type as shown in the formula (1) as long as the Mw is 30,000 or more and 800,000 or less. It may be a distributed type as is selected without any particular limitation. Moreover, what contains polar monomers, such as a nitrogen compound and polyalkylene glycol ester, and the thing containing elemental components other than hydrocarbon may be sufficient. In addition, even if a part of the structure is a polymer compound other than polymethacrylate, a copolymer having a polymethacrylate portion, for example, polymethacrylate copolymerized using at least one of ethylene, propylene, butylene and the like as a raw material Olefin copolymer copolymers, polymethacrylate-polystyrene copolymers and the like can also be used. Good low temperature viscosity characteristics can be obtained by using a polymethacrylate viscosity index improver.
