Alkyl ketal esters as dispersants and slip agents for particulate solids, methods of manufacture, and uses thereof

摘要

Disclosed herein is a dispersion comprising a liquid or semi-solid continuous phase, a dispersed solid phase comprising a plurality of organic, inorganic or inorganic-organic particles, and an alkyl ketal ester having the structure;
wherein a is 0 or an integer of 1 to 12, specifically 1 to 6, more specifically 1 to 4; b is 0 or 1; R2 is a divalent C1-8 group optionally substituted with up to 5 hydroxyl groups; and R1 is C1-6 alkyl, and wherein at least a portion of the alkyl ketal ester is present in the continuous phase, on a surface of at least some of the dispersed particles, or a combination thereof.
