Claim 1
Independent Claim
101 words
THE METHOD OF PRODUCING NOVEL POLYMER COMPOSITIONS WHICH COMPRISES PREPARING AN INTIMATE MIXTURE AT APPROXIMATELY 50 DEGREES C. OF AT LEAST ONE VINYL BASE POLYMERIZABLE MONOMER WITH A PARAFFINIC HYDROCARBON COMPOSITION OF AT LEAST ONE HYDROCARBON OF THE TYPE CNH2N+2, CONTAINING NOT MORE THAN 20% OF UNSATURATED HYDROCARBONS AS IMPURITIES THEREIN AND HAVING A BOILING POINT ABOVE 300*C. AND THE METLING POINT BELOW 70* C., ALLOWING SAID MIXTURE TO COOL SLOWLY TO 20*C. SO AS TO SET INTO A STABLE HOMOGENEOUS GEL, AND EXPOSING SAID GEL TO HIGH ENERGY, IONIZING RADIATIONS UNTIL IT HAS RECEIVED A TOTAL DOSE OF 1,500,000 ROENTGENS.
