摘要：A process for the production of virtually full density polyolefin suitable forfurther processing by drawing to form a high tenacity, highly oriented polyolefin sheetcomprising: a) feeding a metered amount of polyolefin powder into the nip between two
heated calender rolls; b) rolling the powder through the nip under these conditions untila coherent sheet of polyolefin is produced. According to a highly preferred embodiment,initially, the nip is set at a gap smaller than the size of the smallest polyolefin powderparticle and at a temperature above the melting point of the powder and once acoherent sheet of polyolefin exits the nip the temperature in the nip is lowered to atemperature below the melting point of the polyolefin powder and the gap increased toa desired level above the thickness of the largest powder particle.
