Abstract:
A blend which comprises;A) a heterogeneous or homogenous linear ethylene homopolymer or interpolymer and B) a branched homopolymer or interpolymer selected from the group consisting of LDPE, EVA, and EAA; and â€ƒwherein said blend has; 1) a melt index, I2, of about 0.05 to about 20 g/10 min; 2) a flexural modulus of &gE;100,000 psi; 3) a melt strength of &gE;2 cN; 4) a melt extensibility of &gE;25 mm/sec; 5) a UST greater than about 115Â° C.; and 6) wherein said melt strength of said blend meets the following inequality; Melt strength&gE;FMS*[(f*A)+((1âˆ’f)*B)]â€ƒwhere A=3.3814*(I2)âˆ’0.6476 and B=16.882*(I2)âˆ’0.6564; I2 is the measured melt index of the blend; f is the weight fraction of the linear component in the blend, and FMS is &gE;1.1.
