Abstract
"COMPOSIçãO DE óLEO LUBRIFICANTE COM BOAS PROPRIEDADES COM RELAçãO AO ATRITO". A presente invenção refere-se a uma composição de óleo lubrificante tendo boas propriedades com relação ao atrito, a referida composição compreendendo um óleo lubrificante e pelo menos um aditivo que tenha propriedades de redução de atrito. A referida composição é caracterizada pelo fato de que o aditivo com propriedades de redução de atrito é um copolímero em bloco que compreende segmentos hidrófobos P e segmentos polares D. Os referidos segmentos hidrófobos são obtidos através da polimerização de composições de monómeros que compreendem a) entre 0 e 40% em peso, com relação ao peso das composições de monómeros, para a preparação dos segmentos hidrófobos, de pelo menos um ou mais compostos de éster etilenicamente não-saturados da fórmula (I) na qual R é hidrogênio ou metila, R¬ 1¬ representa um radical alquila linear ou ramificado compreendendo entre 1 e 5 átomos de carbono, e R¬ 2¬ e R¬ 3¬ representam cada um independentemente hidrogênio ou um grupo da fórmula -COOR<39> qual R<39> representa hidrogênio ou um grupo alquila que contém entre 1 e 5 átomos de carbono.
