The additions of conventional motor oils can be divided into five groups by virtue of their function. In the first group, there are high ranges of Mn 5,000 to 2 0 0 0 0 0), additions, . polymers and copolymers that predominantly act as viscosity modifiers, viscous indene adhesives and freezing point reducers.

By incorporating the polar basic groups into the structure of the copolymers, the detergents may be dispersants (hereinafter referred to as "EID11"), the use of which allows some reduction in the concentration of DD and it is low the molecular weight of the µn < 2000) in engine oil compositions. The most well-known additives are ρα1ymety 1ak γ 1 (β 1 A i) and their derivatives, k c; polymers of ethylene-propylene (OCR); n n (S B C F '5 a p o 1 y i z o p r n n (F' IP)

Low-molecular-weight additives (Mn < 2000) are mostly used as the ash-free Bd ..., amide, amide, and esters thereof, and the amine salts are used. á z e s :; in the base layer, the base layer and the like, and the like. This is a range of compounds that use very important effects. \ T

This group includes, for example, metal-containing detergents, antioxidants, corrosion inhibitors, friction modifiers, dietary additives, and foam-reducing additives, and a variety of variations are known, and are based on laboratory experiments and brake tests generally selected and used with respect to their interaction, which may act synergistically. c k y a 1 e b o a n t a g o n i e; t i. c :: k y.

During the development of the past 5 years, the composition of engine oils has changed, on the one hand, due to the use of new additives with enhanced effects that are better suited. new requirements, on the other hand, modifying the structure previously with the success of the additives used, i.e., the preparation of additives which, in addition to the main effects, have side effects, and their use allows a further increase or decrease in the concentration necessary to achieve a certain effect. for example, by chemical modification of the additive structure present in the compositions, such undesirable effects are reduced, such as damage to the sealant or corrosion of the material 1a of the bearings, the effect of which is exemplified by modification 865 or 451 380) , ashless ad. in the succinimide (E P 0 537 by optimizing the structure of the polymers used for the synthesis of compounds for synthesis).

By bonding the polar groups to the molecules, the copolymers of the copolymers, commonly used in the art, are copolymers or enhancers. the index of the rye index was successfully obtained in the most important D D - E F '0 400 8e; 6) "Z m e s i. o y e t á á á á á á á á á - - - - - - - - - - - - -:::::::::::::::::::::::::: f i k o o '' " o in vi. s k o z i. t y and wrong o v o. s k o z. t n é h c i n d e; ·: u "

The use of strong inorganic acids has successfully reduced the harmful effects of the customary succinimide-based adducts of succinimide derivatives, S, S, 13.4, 402), F.sub.2. those novel base derivatives and zinc salts of succinic acid polyisobutylene derivatives according to EP 0 051 998 have enabled an increase in the oxidation resistance of oil compositions.

In addition to the high DD ' s effect and the increased storage stability, the process of Er 0 051 .998 using succinic acid esters of succinate gave an excellent reduction in friction by succinic acid and fatty acids.

Additives that are next to increased DD ..... effect and increased to o m p and t i. b i.

Additives (LIS 4 234 435, WQ 91/04959, WO 90/03 359 and EP 0 271 937). The production of such additives with average molecular weights of up to several tens of thousands has been made possible by the synthesis of acylating agents which in their molecules contain more than one chain of each new chain as one succinic anhydride (Bernsteisäureanhydride BA 5 ").

Additives such as alkanolamines, even polyolefins having a higher average molecular weight than usual, can be prepared by reacting such product intermediates, polyamines and / or polyalcohols. with bulky polar groups (imides, amides or esters) and high BD-effect. Structures known c h ad i t. However, the known processes for their preparation vary, but in all cases it is possible to demonstrate in the compositions containing such additives an increase in DD ... and a side effect of viscosity modification and in improving the viscosity index which allows for the reduction of conventional polymers needed to achieve a certain viscosity of 10 to 30% and thereby reduce the cost of additivation.

Despite the achievements in the development of high molecular weight kits: x n x m x d or < Mn > 2,000) described in. Previously, the use of conventional polymers as viscosity modifiers and viscosity index enhancers in the manufacture of multipurpose engine oils continues to be necessary.

The amount of polymers used as viscosity modifiers and viscosity index enhancers can be reduced, for example; using base oils prepared by a hydrocracking process or synthetic base oils (poly-s-olefins, diesters and the like) with higher viscosity indices. "Conventional polymers used as viscosity modifiers and viscosity index enhancers have a beneficial effect on the quality of lubricating oils, but the products that arise when used in decent compositions and the volatile intermediates that result from the formation of chemical impurities promote the presence of extreme conditions (high temperature and mechanical stress) the formation of insoluble resins of bitumen character and thus clogging of the engine. Due to the decrease in molecular weight caused by this decomposition, it is difficult to provide the desired viscosity and viscosity index. Therefore, the quality of engine oils can be further enhanced by the use of polymers with increased stability. 4

Ea.cl.s., t.ala .....- y..mal, ts2.u We came here during our research. to the unexpected knowledge that by using a certain amount of suitably selected bags of greasy oils, various conventional additives of the novel poly functional ashless composition of DD ... additives, engine and lubricating oil compositions can be made with high durability in which conventional polymeric viscosity modifiers and viscosity index enhancers are only included to a limited extent or are not included at all;

The comonomer may be separately added compound or initiator (used in the reaction), incorporation compound, unsaturated decomposition product of the starting polyolefin, or unsaturated degradation product 7

The reaction can be carried out

PolyDlephine EP 0 658 572) by sequentially attaching melein anhydride and comonomers to a polyolefin and / or adding a chain of a copolymer prepared beforehand from a melamine anhydride and one or more comonomer molecules to the polyolefin. The synthesis of the acylating agent is based on the maleic anhydride / comonomer / polyolefin ratio of 1.2-5.5: 0.0-0.5-3; 1 and the reaction is carried out in the presence or absence of a solvent and in 5 to 25% by weight (based on maleic anhydride and 0.1 to 5% by weight of compound controlling the degree of incorporation of the monomers at a pressure of 100 to 1500 kPa at the hydrocarbon or inert atmosphere at temperatures in the range of 80 to 130 ° C.

This is obtained between a long non-polar chain product and a strong polar chain of a copolymer with a static or alternating structure, which is very suitable for the preparation of imid, ester, amide and ester amide derivatives with excellent dispersing properties. the moieties attached to this polyolefin chain may be the same or different. When working with these starting materials, the resulting polyfunctional terminal structures, which mostly contain a large number of carboxyl groups, allow the use of the corresponding, at least bifunctional basic reagents, to produce polymeric structures that appropriately affect the flow properties of the lubricating oils. Indeed, it has been found that with the use of a medium with a numeric medium. molecular weights of more than 800, preferably greater than 2000, are obtained which have good dispersing and detergency effects, and are better viscosity modifiers and viscosity indexers 8 as polyisobutylene-based starting materials. Particularly suitable for the preparation of such polyirucleic chains are the high isocyanate derivatives of x-olefins (x-olefins (> 70 wt.%).

It is particularly advantageous to consider that the polyisobutylene derivatives according to the invention can be used as viscosity modifiers in both the high and the high viscosity fields.

According to our experimental findings, the polyfunctional ashless additive composition has better thermal and oxidation stability than conventional viscosity index enhancers, and therefore the stability of engine oil compositions is increased in an unexpected manner.

Compatible with seal material

A known drawback of conventional succinimide detergents is that, especially at concentrations above 3 to 4%, they cause undesirable deterioration of the sealants, rolling in the motors and based on measurements made with engine oil compositions. 6, K-7, K-8 and K-3, the good compatibility of these compositions with sealants was found. As a comparative result, the results obtained with the composition of Example 5 containing the conventional succinimide (Komad ... 301) were used. various elestomers and the VW-3344 assay under difficult conditions of VW-3344 at which fluoroelastomer was exposed to these compositions. results are shown in Table 6,

One of the greatest advantages of the compositions of the present invention is that the novel additives exhibit enhanced efficacy as viscosity modifiers and viscosity index enhancers.

This effect is evident from the data contained in Table 8, 22, which relates to the results of tests of three compositions, such as mineral oil base compositions SAE 15W-40, partially synthetic composition grade SAE 10W-40, and synthetic composition grade SAE 5W-50, containing the conventional additive Komad-301 and poly functional ashless additive composition with the detergent-detergent effects of the present invention, the compositions having the same composition with respect to other ingredients »The most important Theological data are shown in Tables 8 and 9. of individual viscosity grades adjusted by changing the viscosity of the base oil and the amount of polymer used as a viscosity modifier to almost the same level »

The increase in viscosity caused by the additive composition 1-1 is lower compared to the increase caused by the second polyfunctional ashless additive composition with dispersant-detergent effects, but also increases the viscosity-modifying effect of the polymer in SAE 15W-50 by one a third compared to the amount needed when comparative additive Komad-301 is used; j. polymer savings, about 25% and about 15% at 5W-50.

The PIBF'S 1-2 additive composition, which has a higher effect than the viscosity modifier, allows for the amount of polymer used as the viscosity modifier for SAE grade 15W at the concentration required to achieve the SG rating of the API for the K-4 and K--compositions. ... 40 and 10W-40. In the SAE 5W-50 oil composition, the use of the additive composition F'IBPSI-2 reduced the consumption of the polymer acting as a modifier. t y, o p r. p o r o v n c a n d i t i n d e d D - c o n c i i n d e n d o n one third. 2 comparisons of hot and cold viscosities, and that of i n d i n th e th e t i n t i n t i o n t i n e, that they are very close and that DD ... additives used in the additive mixtures, do not increase the viscosity of the oils more cold than the conventional polymers used as viscosity modifiers. 23 C ···!
