| titleOfInvention | FILMS OF POLYMER BLENDS. |
| abstract | A film comprising a heterogeneous mixture of: 1) from 60 to 99 percent by weight of one or more semi-crystalline polymers (based on the weight of the semi-crystalline and semi-morph polymers), each semi-crystalline propylene polymer comprising 0 to 5% in alpha-olefin comonomer weight (based on the weight of the polymer), each of said semicrystalline polymers having a melting point between 100 and 170 ° C and a melt flow rate of 200 dg / min or less and 2) of 1 to 40% by weight of one or more semi-morph polymers (based on the weight of the semi-crystalline and semi-morph polymers), each semi-morph propylene polymer comprising and 10 to 25% by weight of one or more alpha-olefin comonomers of 2 carbon atoms and / or 4 to 10 carbon atoms, each of said semi-morph polymers having: a) heat of fusion of 4 to 70 J / g; b) a melt flow rate of 0.1 to 200 dg / min; c) an intermolecular composition distribution when determined by thermal fractionation in hexane so that 85% by weight or more of the polymer is isolated as one or two soluble, adjacent fractions, with the polymer equilibrium in immediately preceding or successive fractions and in which each of these fractions has a comonomer content in% by weight with a difference not greater than 20% by weight in relation to the average weight% comonomer content of the copolymer; d) an Mp / Mn of 1.5 to 4, e) a tacticity of propylene triads, when measured by 13 C NMR, of 75% or greater; where the mixture has: i) a melt flow rate of 0.5 to 100 dg / min and ii) 0 to 5% by weight of charge, based on the weight of the polymers and the charge and iii) a turbidity of 20 % or less measured on a small injection molded fragment, 1 mm thick iv) a permanent deformation greater than 65%; in the heterogeneous mixture of semicrystalline and semi-morph polymers, the semi-crystalline polymer being the continuous phase and the semi-morphine polymer being the discontinuous phase and where the film is 0.1 to 25 mil. (2.5 to 635 micrometers) thick and has: a turbidity of 10% or less, a 1st module of drying traction of 100,000 to 30,000 psi (690 MPa to 207 MPa), an Elmendorf tear in the machine direction 45 g / mil. or more (1.77 g / micrometer or more), an Elmendorf tear in the transverse direction of 45 g / mil. or more (1.77 g / micrometer or more), a total impact energy of 3 J or more and a brightness at 45 degrees of 82 or more. |
