    摘要： A polymeric composition suitable for blown film applications comprising a) 80 to 99.5 percent by weight of a continuous polymeric phase comprising a polyolefin, and b) 0.5 to 20 percent by weight of polymeric particles having i) an average particle diameter of 0.85 to 20 μm; ii) a refractive index from 1.46 to 1.61; iii) an average particle hardness from 1.2367E+10 N/m2 to 8.4617E+10 N/m2; and iv) at least 60% polymerized acrylic monomer units, is disclosed. The polymeric composition can be used to form blown film characterized by having a thickness in the range of from 5 to 350 μm, a modulus of elasticity in the range of from 5 to 133 MPa, a melt strength in the range of from 4 to 40 cN, an elongation at break in the range of from 100 to 1000%, a 45 degree gloss in the range of from 7 to 136 and a softness measured by human panel handfeel-ranking methodology, measured by ISO 8587 Sensory analysis that is higher than a film which does not contain the polymeric composition.

    摘要： In the construction of a multilayer film in which an ethylene-based polymer layer is joined to one another layer by a polyurethane (PU) adhesive, the rate of cure and the degree of cure of the PU adhesive are accelerated by incorporating into the ethylene-based polymer layer a functional compound with active hydrogens, e.g., a polyol, and/or a cure catalyst, e.g., an amine, zinc or tin-based compound. The catalyst and reactive functionality may be present on the same molecule (e.g. alkoxylated amine or zinc ricinoleate). The catalyst and isocyanate reactive compound will migrate into the PU adhesive over time and accelerate the rate and promote the degree of PU adhesive cure, and the functional compound will promote the migration of the cure catalyst into the PU adhesive. In turn, this accelerated cure inhibits the migration of residual, monomeric amines from the PU adhesive into and through the ethylene-based polymer.
