CORE-SHELL POLYMER HAVING HYDROPHILIC SHELL FOR IMPROVED SHELL COVERAGE AND ANTI-BLOCKING PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a core-shell polymer having a high level of core material of 75-95 wt.%. SOLUTION: The core shell polymer has a hydrophilic copolymer shell, and a high level of core material of 75-95 wt.%. The hydrophilic shell provides better coverage of the core resulting in better powder properties such as antitack property. The hydrophilic shell also allows for a thinner shell and a larger elastomeric core. The core-shell polymers are especially useful as impact modifiers for plastic materials.
