Abstract: A COLD FORMABLE SANDWICH STRUCTURE WHICH HAS A THERMOSETTING RESINOUS CORE BETWEEN FACE SHEETS COMPRISING LAMINAE OF A THERMOPLASTIC SHEET WHICH INCORPORATES A METALLIC FOIL. THE METAL FOIL-THERMOPLASTIC RESIN FACING SHEETS ARE OF SUFFICIENT THICKNESS AND STRENGTH SO THAT THE SANDWICH CONTAINING THE THERMOSETTING CORE BETWEEN THE FACE SHEETS MAY BE COLD-FORMED INTO SHAPED ARTICLES AND SUCH SHAPES AS IS IMPARTED TO IT IS RETAINED BY THE THERMO-

PLASTIC FACE SHEETS WITHOUT EXTERNAL CONSTRAINT ON THE SHAPE AS THE THERMOSETTING CORE IS SUBSEQUENTLY CURED AT RELATIVELY HIGH TEMPERATURE.

Abstract: 4-CARBOXY-2-PIPERIDONE POLYMERIZES READILY ON HEATING ABOVE ITS MELTING POINT TO AFFORD A POLYMER CONSISTING ESSENTIALLY OF RECURRING UNITS OF THE STRUCTURE:

-((CH2)2-(2,5-DI(O=)PYRROLIDIN-3,1-YLENE))-

THIS POLYMER FORMS TRANSPARENT FILMS, FILAMENTS, AND COATINGS OF HIGH STRENGTH AND GLASS TRANSTITION TEMPERATURE.

Abstract: DIALKYL ESTERS OF ITACONIC ACID REACT READILY WITH HYDROGEN CYANIDE TO FORM DIALKY CYANOMETHYL SUCCINATES WHICH, UPON CATALYTIC HYDROGENATION, FORM MONOALKYL ESTERS OF 4-CARBOXY-2-PIPERIDONE. SAPONIFICATION OF THE ESTER AFFORDS THE FREE ACID, 4-CARBOXY-2-PIPERDONE, WHICH READILY UNDERGOES POLYMERIZATION TO A NOVEL AND HIGHLY USEFUL POLYMER.
