Title:
COALESCING AGENT DERIVED FROM DIOXOLANE DERIVATIVES
Document Type and Number:
WIPO Patent Application WO/2018/004473
Kind Code:
A3
Abstract:
The present invention relates to a coalescing agent as represented in structure (I); wherein; n is integer from 1 to 8; R1 and R2 independently represent group selected from hydrogen atom, alkyl, alkenyl, alkynyl, phenyl, benzyl groups, or optionally cyclic hydrocarbon containing heteroatom; and Y represents group selected from alkyl, alkenyl, alkynyl, phenyl, benzyl groups, or cyclic hydrocarbon containing heteroatom. The said coalescing agent can be used in coating application with efficacy to provide smooth consistent film with chemical and scratch resistant and has no pungent odour, wherein the preparation method of this compound is simplify and employs less harmful chemicals.
