DUBLIN, Ireland--(Business Wire)--
Research and Markets
(http://www.researchandmarkets.com/reports/c92352) has announced the
addition of "Degradation and Stabilisation of Polyamides" to their
offering.

   Linear polyamides are one of the more important classes of
polymeric materials, with wide application in the fields of fibres and
plastics. In general, these polymers may be synthesised in one of two
ways, either by the reaction of dicarboxylic acids (or their
derivatives) with diamines, or from specific amino acids or their
cyclic derivatives the lactams. These two approaches result in two
types of polyamides.

   The polyamides are usually referred to as condensation polymers.
The polyamides thus differ markedly in their manufacturing process
from the polymerisation methods used to manufacture addition polymers
such as styrenics and polyolefins.

   The properties of polyamides when fabricated into articles of
manufacture are considerably affected by the amount of crystallinity
present. Unlike other polymer classes, the degree of crystallinity of
the polyamides can vary by as much as 40%, depending on how the
fabrication is carried out.

   A great deal of research has been carried out into the degradation
of PA, but the materials and test conditions used vary tremendously,
even for a single polymer such as Nylon 6, therefore it is not really
surprising that many such studies differ considerably in both results
and in their interpretation. This report looks at some of the methods
used to stabilise the polyamides and also examines how they degrade
and how this can be prevented by stabilising the molecule.

   This review will be of interest to everyone who works with or
studies polyamides. It is accompanied by around 400 abstracts compiled
from the Polymer Library, to facilitate further reading on this
subject. A subject index and a company index are included.
