摘要	A CROSS-LINKED OLEFIN POLYMER IS PRODUCED BY APPLYING HIGH ENERGY IONIZING RADIATION TO A MIXTURE OF THE OLEFIN POLYMER AND TRIVINYL ISOCYANURATE IN AN AMOUNT SUCH THAT THE MIXTURE ABSORBS A RADIATION DOSE OF BETWEEN ABOUT 1.0 AND ABOUT 1 MEGARAD. THE TRIVINYL ISOCYANURATE SERVES TO ENHANCE THE CROSS-LINKABILITY OF THE OLEFIN POLYMER SUCH A HIGH DEGREE OF CROSS-LINK IS ACHIEVED WITH A SMALL RADIATION DOSE. THE MIXTURE CAN ALSO CONTAIN A FOAMING AGENT WHICH CAN BE MADE TO EXPAND AND THEREBY PRODUCE A CELLULAR PRODUCT. PRODUCTS FASHIONED OF THE CROSS-LINKED POLYMER HAVE IMPROVED DIMENSIONAL STABILITY AND ARE MORE RESISTANT TO THERMAL SHRINKAGE AND DISTORTION. THE CROSS-LINKED OLEFIN POLYMER CAN BE FASHIONED INTO A VARIETY OF PRODUCTS HAVING UTILITY IN MANY FIELDS INCLUDING THE PACKAGING AND CONSTRUCTION INDUSTRIES.
