Elongational behavior of low density/linear low density polyethylenes

Polymer Engineering & Science, 1988
AbstractRheological data have been collected in isothermal elongational flow for three different types of blends, made from one low density polyethylene and three linear low density samples. In addition to the transient curves, elongation at break data are also reported.

Flow properties of low density/linear low density polyethylenes

Polymer Engineering & Science, 1986
AbstractRheological data have been collected both in shear and non‐isothermal elongational flow on three different types of blends, made from one low density polyethylene sample and three linear low density polyethylene samples.In addition to the flow curves, data are presented on the extrudate‐swell phenomenon, on the instability arising in capillary ...

Elongation viscosity estimates of linear low‐density polyethylene/ low‐density polyethylene blends

Polymer Engineering & Science, 1992
AbstractThe elongational viscosity (EV) of two series of linear low‐density polyethylene/low‐density polyethylene blends was estimated using an entry flow analysis. The difference, t − n, between the power law index t of the elongational viscosity and the power law index n of the viscosity, is proportional to the LDPE content for both series of blends ...

Polyethylene, Linear Low-density

2009
Abstract Introduction LLDPE is the common name for copolymers of ethylene with α-olefin comonomer. The comonomers most frequently used commercially are butene, hexene, and octene. Commercial grade LLDPE resins with 4-methyl-1-pentene (4-MP-1) as comonomer is also available.

Photo-oxidation of blends of low density polyethylene and linear low density polyethylene

Polymer Degradation and Stability, 1985
Abstract Films of blends of low density polyethylene with linear low density polyethylene and of the pure polymers were photo-oxidised for different times. From mechanical measurements the rate of photo-oxidation seems greater for the linear low density polyethylene and its rich blends.
