Bio-based terephthalic acid (bio-TPA), bio-based dimethyl terephthalate (bio-DMT), and bio-based polyesters, which are produced from a biomass containing a terpene or terpenoid, such as limonene are described, as well as the process of making these products. The bio-based polyesters include poly(alkylene terephthalate)s such as bio-based poly(ethylene terephthalate) (bio-PET), bio-based poly(trimethylene terephthalate) (bio-PTT), bio-based poly(butylene terephthalate) (bio-PBT), and bio-based poly(cyclohexylene dimethyl terephthalate) (bio-PCT).

Bio-based terephthalate polyesters

Nanocomposites comprising a sulfonated telechelic polycarbonate and an organically modified clay are disclosed. The polycarbonate nanocomposites have improved physical and mechanical properties.

Polycarbonate nanocomposites

A composition comprises, based on the total weight of the composition, from 30 to 50 weight percent of an ionomeric telechelic polyalkylene ester comprising from 0.05 to 5 mole percent of sulfonate end groups; from 50 to 70 weight percent of a polycarbonate; from 0.1 to 10 weight percent of an organoclay; and from 2 to 12 weight percent of an impact modifier.

Telechelic polyester/polycarbonate/organoclay nanocomposites, and related methods and articles

A sulfonated telechelic polycarbonate is described which is produced by melt synthesis. A dihydroxy compound is reacted with a sulfobenzoic acid salt, then with an activated carbonate. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.

Sulfonated telechelic polycarbonates

The present invention provides carboxy-terminated oligomeric polyester compositions useful in the preparation of 'weatherable' polymeric materials, for example weatherable copolyestercarbonates. In one aspect the present invention provides an oligomeric polyester composition comprising structural units derived from at least one diacid, at least one diaryl carbonate and at least one diol. The structural units derived from the diacid are present in a molar excess of from about 10% to about 40% based on a ratio of moles of diacid-derived structural units to moles of diol-derived structural units present in the oligomeric polyester composition. The oligomeric polyester composition is further characterized by the presence of at least some phenoxy end groups.
