ASTM D 5017 Document Information:
Title
Standard Test Method for Determination of Linear Low Density Polyethylene (LLDPE) Composition by Carbon-13 Nuclear Magnetic Resonance
ASTM International
Publication Date:
Dec 10, 1996
Scope:
This test method determines the molar composition of copolymers
prepared from ethylene (ethene) and
a second alkene-1 monomer. This second monomer can include propene,
butene-1, hexene-1, octene-1,
and 4-methylpentene-1.
Calculations of this test method are valid for products containing
units EEXEE, EXEXE, EXXE, EXXXE,
and of course EEE where E equals ethene and X equals alkene-1.
Copolymers containing a considerable
number of alkene-1 blocks (such as, longer blocks than XXX) are
outside the scope of this test
method.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use. See
Section 8 for a specific hazard statement.
