ETHYLENE BASED COPOLYMER COMPOSITIONS AS VISCOSITY MODIFIERS AND METHODS FOR MAKING THEM |
摘要 |
<p>Polymeric compositions and methods for making and using the same are provided. The polymeric composition can include a first ethylene-based copolymer and a second ethylene -based copolymer. The first ethylene-based copolymer can have a weight percent of ethylene-derived units based on a weight of the polymeric composition (EA) ranging from about 35 wt% to about 52 wt% and a weight-average molecular weight (MWA) of less than or equal to 130,000. The second ethylene-based copolymer can have a weight percent of ethylene-derived units based on the weight of the polymeric composition (EB) ranging from about 65 wt% to about 85 wt% and a weight-average molecular weight (MWB) of less than 130,000.</p> |
