Heterogeneous crystallisation of polyethylene terephthalate. A study of the influence of organic and inorganic additives on the rate of crystallisation of polyethylene terephthalate and the subsequent changes in morphology and mechanical properties.Ibbotson, C. January 1976 (has links)
The effect of various inorganic and organic additives as possible
nucleating agents on the crystallisation behaviour of P. E. T. and the
suosequent influence on the morphological and mechanical properties
has been examined. Various methods of mixing(: the polymer and
additive were investigated and a method involving the screw-Extrusion
of the polymer and the additive was ultimately adopted. Crystallisation
studies were carried out using differential scanning calorimetry under
dynamic and isothermal modes. The results produced under conditions
of isothermal crystallisation were analysed by means of a computer.
Despite differences between batches of polymer all the additives
with the exception of indigo produced a nucleating effect in the polymer
as indicated by an increase in the rate of crystallisation compared
with that of the base polymer. Two organo-metallic substances
(sodium benzoate and sodium stearate) proved to be the most effective
in this respect by decreasing the degree of supercooling of the polymer
by 20 [degrees].
Morphological studies were carried out on isothermally crystallised
samples, after etching and replication using a transmission electron
microscope. A nodular structure whose dimensions were sensitive to
both the nucleating agent and the temperature of crystallisation was
observed.
Mechanical testing of samples direct from the D. S. C. was carried
out using a compression method. The breaking loads were found to
vary with both the type of nucleating agent used and the
crystallisation temperature chosen. A separate study involving the
exanination of the resulting fracture surfaces by scanning electron
microscopy revealed that a, high breaking load was associated with a
fine discontinuous structure whereas lower breaking loads were
characterised by a more continuous linear appearance. This implies
a higher energy of fracture due to the increased surface area of
the fracture surface of the former.

Development of high shrinkage Polyethylene Terephthalate (PET) shape memory polymer tendons for concrete crack closureTeall, O.R., Pilegis, M., Sweeney, John, Gough, Timothy D., Thompson, Glen P., Jefferson, A., Lark, R., Gardner, D. 01 February 2017 (has links)
Yes / The shrinkage force exerted by restrained shape memory polymers can potentially be used
to close cracks in structural concrete. This paper describes the physical processing and
experimental work undertaken to develop high shrinkage die-drawn Polyethylene
Terephthalate (PET) shape memory polymer tendons for use within a crack closure system.
The extrusion and die-drawing procedure used to manufacture a series of PET tendon samples
is described. The results from a set of restrained shrinkage tests, undertaken at differing
activation temperatures, are also presented along with the mechanical properties of the most
promising samples.
The stress developed within the tendons is found to be related to the activation temperature,
the cross-sectional area and to the draw rate used during manufacture. Comparisons with
commercially-available PET strip samples used in previous research are made, demonstrating
an increase in restrained shrinkage stress by a factor of two for manufactured PET filament
samples. / Thanks must go to the EPSRC for their funding of the Materials for Life (M4L) project (EP/K026631/1) and to Costain Group PLC. for their industrial sponsorship of the project and author.
