DEFINITION

Classification: 521/76

Preparing a cellular product utilizing a stated ingredient which is surface coated or is a discrete solid particle containing a fluid encapsulated therein, processes of forming an expandable composition, containing said stated ingredient or composition therefrom:

(under subclass 50) Subject matter wherein cell formation is achieved or initiated in the presence of (1) a material which is surface coated; or (2) a material which consists of a particle comprising a fluent material encapsulated in a shell.

(1) Note. The material can be present for any purpose, e.g., reactant, solid polymer, stated ingredient, etc.

(2) Note. This subclass provides (1) for processes of forming cellular products in the presence of a material which

is surface coated or in the presence of an encapsulated fluid; or (2) compositions which are capable of forming a cellular product and which compositions contain an encapsulated fluid or surface coated material; or (3) processes of preparing a cellular forming composition containing a surface coated material or encapsulated fluent material.
