The present disclosure provides a polyester including residues of formulas (i), (ii), (iii), and (iv): for example, terephthalic acid, for example, ethylene glycol, for example, cyclohexanedimethanol, and for example, tricyclodecane dimethanol,

Polyester and molded article

A polyester is provided. The polyester comprises:

Polyester

Disclosed is a polyester and molded article. The polyester includes residues of formula (i), formula (ii), and formula (iii): in which Ris an arylene group; Ris a C-Cstraight-chain hydrocarbylene group; and * represents a linking bond. The polyester has a number average molecular weight not less than 15,000 and has a degree of dispersion ranged from 2.95 to 5.70.

A polycarbonate polyester includes residues of following formula (1), formula (2) and formula (3): 

Polycarbonate polyester

An aliphatic polyester is provided. The aliphatic polyester comprises: wherein Ris absent or a C1 to C40 aliphatic hydrocarbyl; wherein Ris a C1 to C10 aliphatic hydrocarbyl; and

Aliphatic polyester with high elongation

Compositions containing Tricyclodecane Dimethanol (TCCDM) and at least a second component, wherein the composition is characterized in a gas chromatography (GC) analysis, wherein the TCDDM is eluted at a retention time ranging from 12.4 minutes to 13 minutes, the second component is eluted at a retention time ranging from 11.8 minutes to 12.4 minutes, and the ratio of the area of elution peaks indicating the second component compared to the area of the elution peaks of the TCCDM is between 0.001:1 and 0.04:1. Useful products of the composition include polymers and optical materials.

Tricyclodecane dimethanol composition and uses thereof

The present invention provides a phosphorus-containing compound of formula (I): wherein R, R, Rand Rare the same or different; and R, R, Rand Rare independently selected from the group consisting of hydrogen, halogen, Calkyl, haloalkyl, and alkoxy. The phosphorus-containing compound is prepared by bonding a bisphenol group to a phosphorus atom to prevent the phosphorus-containing heterocyclic molecule from exhibiting steric hindrance on hydroxyl functional groups, thereby increasing reactivity in the subsequent reactions.
