Although the scope of this review mainly covers CHDM-based polyesters modified with isophthalic acid or ethylene glycol (i.e. PCTA or PCTG, and PETG, respectively), many other copolyesters with interesting properties have been prepared with a variety of other comonomers. [Pg.283]

The selection of monomers for preparation of copolyesters is based on applying established structure/property principles and is usually driven by new market needs and applications with specific end-use properties in mind. Thus, attempts to develop amorphous or semicrystalline CHDM-based polyester compositions for applications requiring greater heat resistance or higher heat deflection temperatures have generally followed the theme of incorporating bulky or rigid constituents to further enhance the desirable thermal properties of CHDM-based... [Pg.287]

In the family of aromatic copolyesters, the best known copolymer based on 1,4-CHDM is poly(ethylene-co-l,4-cyclohexylenedimeth-ylene terephthalate) (PECT) (Figure 6.6). PECT actually embraces a family of copolyesters subdivided into two groups, according to the... [Pg.186]

The first blends studied on polyesters based on 1,4-CHDM were made of the amorphous copolyester of terepthalic and isophthalic acids and 1,4-CHDM (PCTA) and polycarbonate of bisphenol A (126). The single displayed for the whole range of compositions was taken as demonstrative of full miscibility, which is explained as due to the positive physical interactions between the polyester and the polycarbonate. PCTA is also miscible with a copolycarbonate of bisphenol A and l,l-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclo hexanone (TMC) for all compositions except for those involving a polycarbonate entirely made of TMC (127). [Pg.211]
