Melting polyesters

PCT describes a polyester composition prepared from CHDM and DMT (or TPA). The abbreviation PCT is thus derived from the technical name for the polymer, i.e. poly(l,4-cyclohexylenedimethylene terephthalate), or PCT. This material is a highly crystalline, high-melting polyester, with the following structure ... 

Finally, the use of low-melting polyesters for low-melt fibers (melting point, 110-180 °C) should be pointed out, where TPA is replaced partly by IPA or adipic acid for bond fiber application. 

One exception to this rule 1s the low melting polyesters since poly(3-hydroxybutyrate) is a naturally occurring material which many bacteria and fungi use to store energy in the same manner that animals use fat.

Plasticized PVC and vinyl chloride-vinyl acetate copolymers can be wiped with solutions of adipic, maleic, citric, and other acids, giving improved adhesion when bonding with hot-melt polyester adhesives. ... 

The 12C Series of low melting polyester-based TPU is currently being developed for a wide range of specialty engineering plastics. The interesting thermal and rheological properties of this series provide enhanced compatibility with a wide variety of other thermoplastics.
