Class Information
Number: 264/4.33
Name: Plastic and nonmetallic article shaping or treating: processes > Encapsulating normally liquid material > Liquid encapsulation utilizing an emulsion or dispersion to form a solid-walled microcapsule (includes liposome) > With treatment subsequent to solid wall formation (e.g., coating, hardening, etc.) > Microcapsule wall derived from synthetic polymer
Description: Subject matter wherein the microencapsulation process produces a wall derived from a synthetic polymer which was prepared either prior to or during the process.
