Claim 1
Independent Claim
108 words
A TWO COMPONENT COPOLYMER OF MONOMERIC VINYLIDENE CYANIDE AND AN ALKYL ESTER OF ACRYLIC ACID, SAID COPOLYMER BEING A RESINOUS, HEATSOFTENABLE SOLID WHICH IS INSOLUBLE IN ACETONE, THE MONOMERIC VINYLIDENE CYANIDE ENTERING INTO SAID COPOLYMER TO PRODUCE VINYLIDENE CYANIDE UNITS BEING A LIQUID AT ROOM TEMPERATURE AND A CRYSTALLINE SOLID AT 0* C. HAVING A MELTING POINT WHEN IN PUREST FORM OF SUBSTANTIALLY 9.0* TO 9.7* C. AND BEING CHARACTERIZABLE CHEMICALLY BY THE ABILITY TO UNDERGO ON CONTACT WITH WATER AT ROOM TEMPERATURE AN INSTANTANEOUS HOMOPOLYMERIZATION REACTION TO GIVE A SOLID, WATER-INSOLUBLE RESIN AND BY THE ABILITY TO REACT AT ROOM TEMPERATURE WITH BUTADIENE-1,3 TO GIVE SOLID 4,4-DICYANOCYCLOHEXENE
