Title: AQUEOUS POLYMER DISPERSIONS, A METHOD FOR THEIR PREPARATION AND THE USE THEREOF AS POUR-POINT DEPRESSANTS FOR CRUDE OIL, PETROLEUM, AND PETROLEUM PRODUCTS
Abstract:
The invention relates to aqueous polymer dispersions comprising at least one polymer obtaina- ble by the reaction of at least one monomer M1 of the general formula H2C=CH-C(O)OR (I), wherein R is an unbranched alkyl chain comprising from 18 to 22 carbon atoms, and optionally at least one monomer M2. The invention relates moreover to amethod for the preparing of such aqueous polymer dispersionand the use thereof as pour point depressant for crude oil, petrole- um, and petroleum products.
