Bogolyubov's chain of equations for classical one-time correlation functions in a gas with binary collisions is used to obtain an equation for the long-wavelength (ka << 1) part of the binary correlation function g(2)(p(1)r(1), p(2)r(2), t) (a is the radius of the interaction...
b) hydrogenating the resultant branched fatty acids or esters in a manner known per se, and c) esterifying the resultant long-chain, branched alkanols by means of poly(meth)acrylic acid in a manner known per se, are suitable as lubricant additives, in particular as viscosity index improvers...
(A) a polymer comprising a (meth)acrylate containing a constituent unit (1) represented by the following formula (1): wherein R1 is a hydrogen atom or a methyl group, and R2 is a long-chain alkyl group of 12 to 28 carbon atoms, and (B) a crosslinking agent comprising an amino re...
5. A copolymer according to claim 2 wherein R4is a straight- chain or branched alkylene group with 1 to 6 carbon atoms. 6. A copolymer according to claim 2 wherein R8is a methylene group. 7. A copolymer according to claim 2 wherein R8is a C1-C5-mono alkyl-substituted ethylene group...
The invention concerns a method for conditioning long chain alkyl acrylate of general formula (I) in which n is between 18 and 60, said acrylate can also be in the form of a mixture of acrylates (I) with chain length ranging between 18 and 60 carbon atoms. The invention is characterised...
Copolymers of long-chain alkyl acrylates corresponding to the following formula CH2=CR1-CO-OR2 (I) in which R1 is a hydrogen atom or a methyl group and R2 is the residue of a C16-34 fatty alcohol, with N-containing olefins containing acrylate or methacrylate functions can be used as ...
Copolymers of long-chain alkyl acrylates or methacrylates of the formulaCH.sub.2 ═CR.sup.1 --CO--OR.sup.2 (I) < P>in which R.sup.1 is a hydrogen atom or a methyl group and OR.sup.2 is a fatty alcohol radical with 16 to 34 carbon atoms and nitrogen-containing olefins ...
It is possible to prepare mixtures of linear saturated hydrocarbon with unsaturated or branched fatty acids if needed. Although branches and unsaturated fatty acids may reduce melting temperature, the effect can be compensated for by increasing the length of grafted alkyl chains. If benefit agent is...
26.A process of synthesizing a long-chain branching olefin polymer, the process comprising:providing an olefin monomer;providing a T reagent having the formula: X—R1—Ywherein X is an alpha olefin or norbornene moiety, R1is a C0-C10 linear, branched, or cyclic alkyl or aryl and where Y ...
The invention relates to a process for packaging long-chain alkyl acrylates by mixing them with a sufficient amount of solvent, e.g. xylenes, ethylbenzenes or trimethylbenzenes, thereby facilitating the handling of said acrylates by reducing the melting point of the mixture.Jean-Michel Paul...
