摘要:
The invention relates to a thermoplastic polyester comprising: at least one 1,4 : 3,6-dianhydrohexitol unit (A); at least one cyclic diol unit (B) other than cyclohexanedimethanol units and 1,4 : 3,6-dianhydrohexitol units (A); and at least one aromatic carboxylic diacid unit (C), said polyester being free from ethylene glycol units. The invention also relates to the production method and use of same.
摘要:
The invention relates to a thermoplastic polymer comprising at least one 1,4:3,6-dianhydrohexitol unit (A), at least one alicyclic diol unit (B) other than the 1,4:3,6-dianhydrohexitol units (A) and at least one high-viscosity terephthalic acid unit (C).
摘要:
The invention relates to a thermoplastic polyester comprising: at least one tetrahydrofuran-dimethanol diol motif (A); and at least one aromatic acid motif (B) selected from terephthalic acid, isophthalic acid, phthalic acid, 2,6-naphthalene dicarboxylic acid and 1,4-naphthalene dicarboxylic acid, the glass transition temperature thereof being higher than, or equal to, 50°C. The invention also relates to a method for producing polyester comprising said motifs (A) and (B).
摘要:
A polyester including at least one furandicarboxylate unit, at least one saturated, linear or branched, diol unit including from 2 to 10 carbon atoms, and at least one bicyclic diol unit, the said bicyclic diol being chosen from: isosorbide, isoidide, isomannide, 2,3:4,5-di-O-methylene-galactitol, and 2,4:3,5-di-O-methylene-D-mannitol. The glass transition temperature of the polyester is greater than or equal to 90° C. Processes for preparing this polyester are also described.
