The absorption bands owing to the alcoholic groups of CHDM diol was almost absent in the IR spectrum of the polyoxalate polymer.
Both CHDM and CHDA exist in cis and trans isomeric forms, with a thermodynamic equilibrium ratio between the trans and cis isomer of 66%.
The viscosity of the paints followed the viscosity of the reactive diluents with CHDM making the most viscous paint.
Chemicals, fibres and plastics company Eastman Chemical Company (NYSE:EMN) said on Friday that it is in the process of expanding its CHDM capacity by 25% at its Kingsport, Tenn., site.
The questions were then compiled and a final list was sent out to CHDM clinician participants just prior to the evaluation session.
The glycol-modified copolyesters are PETG (less than 50% of the diol content is CHDM) and PCTG (more than 50% of the diol content is CHDM).
In order to bring some impact strength properties, Eastman developed the two cycloaliphatic rings: (i) 1,4-cyclohexanedimethanol (CHDM) for PETG in 1980s and (ii) 2,2,4.4-tetramethyl-1,3-cyclobutanediol (CBDO) for Tritan copolyesters (no bisphenol A) since its launch in 2007.
Use of the CHDM monomer in CoPET production (which toughens PET) enables advantages, as shown in Figure 4.
PBCS by incorporation of alicyclic units 1,4-cyclohexanedimethanol (CHDM) into PBS backbone has been extensively investigated on the biodegradability and biocompatibility [14], The chemical composition of PBCS series (PBCSs) plays an important role in controlling the physical properties.
Eastman's family of polyester materials for rigid packaging includes its APET clear amorphous grade (for use to about 140 [degrees] F), for applications such as general-purpose blister packages, clear drinking cups, and dell containers; its CPET higher-temperature opaque crystalline grade, for use to 350 [degrees] F to 400 [degrees] F, for dual-oven-able trays; Eastar PETG 6763, the company's proprietary copolyester grade (for use to 140 [degrees] F) that is highly modified with cyclohexanedimethanol (CHDM), a crystallization inhibitor, for more stringent packaging requirements in markets such as medical and electronic; and PCT, with a temperature capability of 160 [degrees] F, notably for specialty packaging.
to tailor the crystallization rates of its engineering polyesters is its cyclohexanedimethanol (CHDM) glycol monomer, according to Leonard P.
For comparison, [T.sub.g] values of IPA or PETI, and PET containing CHDM (referred to as PETG) are also included in Fig.
