| 181 | Process for producing a porous film | US229797 | 1988-08-08 | US4921652A | 1990-05-01 | Syoichi Tsuji; Syoichi Ito; Shuji Matsumura; Hisatosi Suzuki; Michiyasu Ito |
| A process for producing a porous film having practically sufficient mechanical strengths, good flexibility, uniform fine pores and high moisture vapor permeability, and further an extremely thin porous film, which process comprises blending 30 to 80 parts by weight of an inorganic fine powder having a specific surface area of 15 m.sup.2 /g or less and an average particle size of 0.4 to 4 .mu.m with 20 to 70 parts by weight of a polyolefin resin, followed by melt-molding the resulting blend into a film and then stretching the film to 2 to 7 times the original length at least in the uniaxial direction. | ||||||
| 182 | Process for preparing curable polyolefin polymers | US414646 | 1982-09-03 | US4522957A | 1985-06-11 | Billy H. Ashley |
| The disclosure is directed to improvements in a process for preparing curable polyolefin polymers in which a mass of dry, discrete, free-flowing particles of polyolefin polymer is tumbled in admixture with a curing agent effective to cause curing when the finished product is subjected to curing temperature, which comprises tumbling said mass in two separate and discrete steps in which essentially all of the curing agent is incorporated into said mass in the first tumbling step and equilibration between the curing agent and the polymer is effected in the second tumbling step while maintaining in both tumbling steps a temperature above the melting point of said curing agent but below both the agglomerating temperature and the curing temperature and, at least in the second tumbling step, a temperature which provides equilibration between the curing agent and the polymer; and thereafter tumble-cooling the thus-treated mass until a dry, discrete, free-flowing mass of polymer particles is obtained. The tumbling steps are advantageously effected in a Zig-Zag Blender.TM., wherein incorporation of the curing agent is effected by spraying liquid curing agent onto particles of said polymer while they are separated from said mass and dispersed in the atmosphere which envelopes said mass. | ||||||

| A process for producing a chemically crosslinked polyethylene foam, which comprises heating a polyethylene composition consisting essentially of 97 to 50 % by weight of polyethylene, 3 to 50 % by weight of polybutadiene having a 1,2-addition unit content of at least 70 %, an intrinsic viscosity [.eta.] of at least 0.7 dl/g (as measured in toluene at 30.degree. C), at least one blowing agent and at least one crosslinking agent to foam and crosslink said polyethylene composition.

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.
