    (54)Peroxide concentrate and polymer carrier


    (57) A peroxide catalysts concentrate is provided including one or two polymers chosen with the criteria that the polymers form a homogeneous composition that the melt index composition be in the range of 250 to 2500 grams per ten minutes, that the average softening point of the composition be in the range of 50 degrees to 115 degrees centigrade and that the melting range peaks of the polymer differ by at least 30 centigrade degrees offering improved stability and utility in essentially every kind of processing equipment with essentially no degradation or loss of peroxide activity with the added advantage of being able to use low volatility and highly active peroxides with a one hour half-life down to 95°C.
