VISCOSIFIER COMPRISING FILAMENTOUS POLYMER PARTICLES |
| 摘要 |
The invention relates to the use of polymer particles in the form of filaments formed by block copolymers, as viscosifiers or agents that modify the rheology of organic or aqueous solutions. More specifically, the invention relates to the use of said crosslinked filamentous polymer particles for improving the resistance to heat ageing of an organic or aqueous solution. |

1. A process for increasing resistance to thermal aging of an aqueous or organic solution, said process comprising combining said solution with a latex of filamentous polymer particles, said particles being crosslinked, block copolymers synthesized by controlled radical emulsion polymerization, in the form of cylinders having a length/diameter ratio of greater than 100 and added to said solution at a content by weight of a minimum of 100 ppm. |
