Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
110 words
AN EASILY PROCESSABLE ELASTOMER COMPRISING AN INTIMATE BLEND OF (A) A PLASTIC, BENZENE-SOLUBLE CHLOROPRENE POLYMER AND (B) A CROSS-LINKED, BENZENE-INSOLUBLE CHLOROPRENE POLYMER OBTAINED BY EXPOSING A CHLOROPRENE POLYMER IN LATEX FORM TO IONIZING RADIATION PRODUCING THE EFFECT OBTAINED BY EXPOSURE TO AT LEAST 3X106 RADS OF 0.5 TO 5.0 MEV. BETA RADIATION AT A DOSE RATE OF ABOUT 105 TO 107 RADS PER SECOND, THE RATIO OF (A) TO (B) ON A WEIGHT BASIS BEING BETWEEN ABOUT 1:4 AND ABOUT 4:1, SAID CHLOROPRENE POLYMERS BEING SELECTED FROM THE GROUP CONSISTING OF POLYCHLOROPRENE AND COPOLYMERS OF CHLOROPRENE WITH UP TO ABOUT 10 PERCENT BY WEIGHT OF ANOTHER POLYMERIZABLE ETHYLENICALLY UNSATURATED MONOMER.
