Vitrigens. I. Synthesis and Characterization of Low Molecular Weight Organic Glasses
摘要:
New low molecular weight organic materials with a strong tendency towards glass formation and glass temperatures above room temperature were synthesized. These materials consist of twin molecules where two bulky groups, i.e. carbazole (Ca), 3,6-dibromocarbazole (DBrCa), 2,3-benzocarbazole (BC), 1,2-benzo-3,4-dihydrocarbazole (BCDH), phenothiazine (Ph), 1,8-naphthalic acid anhydride (NI), and pyrene-l-aldehyde (PY) have been linked by flexible or semiflexible aliphatic or aromatic central units. Their structure-glass temperature relationship and some relations between thermodynamic parameters and amorphous properties are discussed.

A wholly aromatic polyester composition comprising
(a) 100 parts by weight of a wholly aromatic polyester containing as a main component at least one compound selected from the group consisting of aromatic dicarboxylic acids, aromatic dihydroxy compounds and aromatic hydroxycarboxylic acids, and
(b) from 5 to 300 parts by weight of a low-molecular-weight compound being substantially non-reactive with the wholly aromatic polyester and having a boiling point of at least about 200°C under atmospheric pressure and a molecular weight of not more than 1.000.
The wholly aromatic polyester composition is produced advantageously by polycondensing in the molten state the polyester-forming starting mixture in the presence of the low-molecular-weight compound.
A film-like or fibrous article of a wholly aromatic polyester may be produced by extracting the low-molecular-weight compound from a film-like or fibrous article of the wholly aromatic polyester composition.
