US Patent:

44915543, Jan 1, 1985

Filed:

Sep 27, 1983

Appl. No.:

6/536332

Inventors:

Roger G. Hamel - Methuen MA
Susan B. Poulin - Woburn MA

Assignee:

Thiokol Corporation - Chicago IL

International Classification:

B29H 720

US Classification:

264141

Abstract:

A one-part activator and blowing agent system for foaming plastics comprising an alkali metal borohydride and a salt hydrate blended in a single pellet or as separate pellets with a dry inert resinous polymer carrier. The one-part system is blended with a resinous polymer and then the blend extruded at a temperature at which the blend becomes molten such that the salt hydrate releases its water of hydration to hydrolyze the borohydride and produce a cellular article.

Ann B. Salamone - Marble Head MA

Assignee:

Thiokol Corporation - Chicago IL

International Classification:

G03F 726

US Classification:

430326

Abstract:

A method of developing a positive photoresist layer which has been image-wise-exposed comprising contacting the layer with an alkaline developing composition to remove exposed areas of the layer, the developing composition comprising a solution containing a cyclic quaternary ammonium hydroxide developing agent in a sufficient concentration to remove exposed areas of the layer. The present invention also includes a developing composition for use in the method.
