POLYMER EMULSIONS WITH BIMODAL MOLECULAR-WEIGHT DISTRIBUTION |
摘要 |
The invention relates to polymer emulsions of poly(meth)acrylic acid esters and olefin copolymers suitable for improvement of the viscosity index, for use as oil additives. The polymer emulsion is formed of a continuous phase of ply(meth)acrylic acid esters and d-oligomers where the esters and oligomers have a bimodal molecular-weight distribution, a stabilizing agent (a graft or block polymerizate of an olefin copolymerizate and methacrylic acid esters), and a disperse phase of olefin copolymerizates distributed in the continuous phase. |
