Said as mentioned, used the high-molecular weight multipolymer in the present composition.The unique restriction in practice of molecular weight is that it must be high enough to eliminate effectively smog, but can not highly operational difficulty must occur.About this point, have been found that the very high multipolymer of molecular weight is difficult to be dissolved in the matrix oil of lubricating oil composition.They also are difficult to filter or topple at low temperatures.Use the very high homopolymer of molecular weight also can cause lubricating oil component unstable relatively.Therefore, the viscosity-average molecular weight of the used multipolymer of the present invention generally is limited in and is not more than about 10,000,000.Usually, ideal multipolymer viscosity-average molecular weight is often greater than 100,000, typically, between about 100,000 to about 10,000, between 000.It is about 500,000 to 10,000 that the molecular-weight average of the multipolymer that the present invention uses is preferable over, and 000 scope, most preferred scope are about 1,000,000 to 8,000,000.Usually, the effect of fog dispersal is along with the molecular weight of copolymer additives increases and increases.
The molecular weight of polymkeric substance can be used the light dispersion method, and assay method (vaporphase osmomelry) is pressed in gas-phase permeation, any mensuration in gel permeation chromatography (GPC) or the similar several method.What the method for some determining molecular weights obtained is weight average molecular weight, and other obtains number average molecular weight or viscosity-average molecular weight.For the purpose of unification, the used term ＂ molecular-weight average ＂ of this specification sheets and claims is meant viscosity-average molecular weight.Typically, viscosity-average molecular weight can be measured with gel permeation chromatography (GPC), being determined at 135 ℃ carries out, with the very narrow polystyrene standard size bead of molecular weight ranges, make solvent with orthodichlorobenzene, in fact, GPC utilizes the size of polymer molecule as a kind of method of determining molecular weight, and this is decided by the fluidic scope.This technology comprises makes polymers soln pass through the cross-linked polymer bed.Less molecule can infiltrate the micropore of cross-linked polymer bed, like this, compares with bigger molecule, and their mobile delays in bed, macromole then flows through micropore still in liquid phase.More situation about GPC, ask for an interview people's such as W.W.Yau Modern Size-Exclusion Liquid Chromatography, Wiley-Intersc-ience (1979), with Waters Associates Liquid ChromatographySolvent Manual, Waters Associates (Millipore Corp) (1983).
In order to produce desirable elimination fog effect, need (represent to the amount of chain saw lubricating oil composition interpolation copolymer additives of the present invention with weight percentage, in other words, the whole lubricating oil composition of per 100 parts of weight, comprise in the composition of multipolymer the parts by weight that multipolymer is shared) different and different according to the characteristic of lubricating oil composition and composition.In some was formed, adding 0.0001wt% or multipolymer still less just can obtain the ideal effect in the lubricating composition.On the other hand, need to add 1.0wt% in some lubricating composition or more multipolymer just can reach ideal effect.But, have been found that and wish to get the ideal effect that the addition of multipolymer is about 0.005 to about 0.5wt% in the chain saw lubricating composition.In preferred embodiments, the amount of the multipolymer that adds in the lubricating composition is about 0.005 to about 0.04wt%.
Because multipolymer is solid when described molecular weight, thus general preferably before use it is dissolved in suitable solution or is suspended in the suitable diluent, because in lubricating composition, add than being easier to the form of solution or suspension.Suitable solvent and thinner comprise kerosene, petroleum naphtha and other petroleum fractionss and unreactive hydrocarbons, as hexane, heptane, octane or materials similar.

Can measure the resistance to fogging that adding high-molecular weight polymer fluid obtains with several technology.A kind of technology atomisation technology (the AtomizerSpray Fechnique) of simple qualitative test resistance to fogging energy.This manipulates a kind of spray bottle that has the pump that can extrude bottle content, and a kind of suitable spray bottle that is used for this method is by the Consolidatded Plastics Company, the Airspray that Twinsburg, Ohio provide
TMSpray bottle.This spray bottle typically is furnished with one group of removable outlet end cap or nozzle, can control the form of the mist that extrudes from bottle.For example, Airspray
TMSpray bottle is equipped with three kinds of nozzles, and being designed to can be with ropy material not (as, water) with thick fog type, mist type, or the form of uperize type extrudes from bottle.
For the effect of multipolymer of the present invention fog dispersal additive is described, the designs of nozzles that spray bottle assembled that sample 14C (heptane in the same old way) is packed into becomes the bottle content to be sprayed with the thick fog type.Press bottle then the heptane sample is depressed into the degree of noting, make the heptane sample be enough in bottle, spray with the thick fog type.
Repeat aforesaid operations (spray bottle needed through cleaning after using at every turn) with sample 1-7 and 8C-13C.Each tested sample is used and the used identical nozzle of control sample (sample 14), with Sprayable with in the same old way Sprayable relatively.Observe, form 1,2,8C-11C and 14C sample spray in bottle with the thick fog type, and form 3-5, and 12C and 13C sample are emitted with the uperize type, have only 6 samples of composition very slightly and discontinuously to flow out, and do not flow out from bottle and form 7.
The result that Atomizer Spray Technique detects charges to table 2.

Table 2 shows that butene-1-laurylene-1 multipolymer can eliminate mist of oil effectively, the fluid that sprays in the spray bottle can be transformed into uperize by mist with low at least this multipolymer to 0.03wt% of concentration.By contrast, the polyisobutene additive of industrial usefulness could disperse fog when its concentration in the heptane carrier solvent reaches 0.23wt% effectively.So,, make the fog dispersal additive than effective more than seven times with the polyisobutene additive with butene-1-laurylene-1 multipolymer according to the result of spray test.
The method of another evaluation and prediction polymerization fog dispersal additive characteristic is to measure the extensional viscosity of various additive solutions.But, not resembling shear viscosity, extensional viscosity is difficult to measure, because fluid can't be caught and elongate under constant speed.A kind of method of measuring the polymers soln extensional viscosity (AM-S) discloses among (the Analytical Method Specification) 89-006 (1990, December) to some extent in Exxon research and engineering corporation's " analytical procedure detailed description ".This method is measured the fracture height (h) of the so-called ＂ tubeless siphon ＂ of a dilute polymer solution, and the ＂ specific viscosity ＂ (h/c) of polymkeric substance, and wherein h is for centimetre to be the height that unit records, and c is that polymkeric substance is at NORPAR 15 solution (C
15Whiteruss) concentration in is in mass percent.In centimetre height (h) be defined as one thin strand of polymers soln can be elongated (constantly) from the container that polymers soln is housed length.Measuring method is, contact the surface of solution with long * 20 standard syringe (tack) syringe needles (0.023in.I.D.) of-3.8cm (linking to each other) with vacuum pump, go up the retaining part vacuum (approximately-40kPa) at polymers soln (about 25 ℃ of temperature), then, relative to the polymers soln surface with 5mm/sec (+/-1mm/sec.) speed moves syringe needle, (as fixedly needle point is motionless, reduce container, or lift high syringe needle above container interpolymer liquid level of solution) comes the siphon polymers soln.When siphon liquid disconnects, measure the distance that needle point leaves solution surface in the container, this distance, in centimetre, be exactly h.So the h value is high more, in other words, long more at cut-off point tubeless siphon fluid column, the fluidic stretchiness is high more.
The specific viscosity of polymkeric substance (h/c) has hinted the anti-mist characteristic of polymkeric substance in the solution, and in other words, specific viscosity is big more, and the fluidic resistance to fogging expectation that is dissolved with polymkeric substance is just good more.Used vacuum should be enough to keep fluid to flow through the constant airspeed of syringe needle, and the vacuum of general pact-40kPa is just passable.Situation is asked for an interview k.k.k.Chao and M.C.Williams more specifically, (J.Rheology) " J. rheology " 27 (5) 451-474 (1983).
