摘要： Extrusion-cast films of high molecular weight, linear, low density ethylene copolymers which inherently have high block and high cling characteristics are compounded with a minor amount of a low molecular weight organic, such as a polyglycol, before being extrusion-cast as a thin film, the low molecular weight organic serving to substantially reduce the block, but retaining high cling characteristics.

摘要： Maleic anhydride-grafted HDPE fibers are disclosed. The processing of LLDPE and fibers is enhanced by including HDPE or LLDPE which has been grafted with maleic anhydride to obtain succinic acid or anhydride groups along the linear polyethylene chain in the fiber feed stock. The fibers are formed by extruding molten LLDPE containing the grafted HDPE or LLDPE through an orifice to form a thin fluid stream, melt drawing the thin fluid stream, and quenching the melt drawn thin fluid stream to form a fine denier strand. Biconstituent fibers of LLDPE and grafted HDPE or LLDPE, mixtures of such fibers with other fibers such as polyester, and woven and non-woven fabrics made from such fibers and fiber blends are also disclosed.

摘要： Elastic ethylene polymers are disclosed which have processability similar to highly branched low density polyethylene (LDPE), but the strength and toughness of linear low density polyethylene (LLDPE). The polymers have processing indices (PI's) less than or equal to 70 percent of those of a comparative linear ethylene polymer and a critical shear rate at onset of surface melt fracture of at least 50 percent greater than the critical shear rate at the onset of surface melt fracture of a traditional linear ethylene polymer at about the same I.sub.2 and M.sub.w /M.sub.n. The novel polymers can also have from about 0.01 to about 3 long chain branches/1000 total carbons and have higher low/zero shear viscosity and lower high shear viscosity than comparative linear ethylene polymers. The novel polymers can also be characterized as having a melt flow ratio, I.sub.10 /I.sub.2, .gtoreq.5.63, a molecular weight distribution, M.sub.w /M.sub.n, defined by the equation: M.sub.w /M.sub.n .ltoreq.(I.sub.10 /I.sub.2)-4.63, a critical shear stress at onset of gross melt fracture greater than about 4.times.10.sup.6 dyne/cm.sup.2, and a single DSC melt peak between -30 C. and 150 C.
摘要翻译：公开了弹性乙烯聚合物，其具有与高度支化的低密度聚乙烯（LDPE）相似的加工性能，但线性低密度聚乙烯（LLDPE）的强度和韧性。聚合物的加工指数（PI）小于或等于对比线性乙烯聚合物的70％，并且表面熔融断裂开始时的临界剪切速率比表面开始时的临界剪切速率大至少50％传统的线性乙烯聚合物在约相同的I2和Mw / Mn下熔融断裂。新型聚合物还可以具有约0.01至约3个长支链/ 1000个总碳，并且具有比对比线性乙烯聚合物更高的低/零剪切粘度和较低的剪切粘度。新颖的聚合物也可以表征为具有由下式定义的熔体流动比，I10 / I2，≥5.63，分子量分布，Mw / Mn，Mw / Mn（I10 / I2）-4.63 ，在大于约4×10 6达因/ cm 2的总熔体断裂开始时的临界剪切应力和在-30℃和150℃之间的单个DSC熔融峰。
