The present disclosure relates to a process for preparing polyester. The process for preparing the polyester essentially involves the preparation of the isosorbide oligomer and the isosorbide polymer from the isosorbide oligomer. The isosorbide oligomer or isosorbide polymer is then co- polymerized with the polyeste...
A method of forming a polymer includes polymerizing a first pre-polymer, produced by the reaction of a dicarboxylic acid, or ester thereof with a first alkylene diol; with a second pre-polymer produced by the reaction of an aromatic sulfonate or a salt thereof, or ester thereof, with a second alkylene diol; to form ...
The present invention relates to a low melt copolyetherester based on terephthalic acid, isophthalic
acid, aliphatic diols and polybutylene terephthalate. The melting point of the low melt
copolyetherester is between 90° to170°C.
The present invention discloses a water soluble co-polyester precursor comprising: (a) at least one
dicarboxylic acid or ester thereof; (b) at least one diol; and (c) at least dimethyl sulfoisophthalate
(DMSIP) or isophthalic acid sulfonate (SIPA) having a weight percentage in the range of 0 to 20
wt% or 0 to 18%...
A biaxially-oriented ultra-heat sealable polyester film includes: a core layer comprising polyethylene terephthalate, post-consumer recycled grade polyethylene terephthalate, and a filler; and a heat-sealable layer disposed on at least one surface of the core layer and comprising a co-polyester composition; wherei...
The present invention discloses a low melt copolyetherester comprising terephthalic acid, aliphatic diols, and combination of antioxidants, wherein the molar proportion of terephthalic acid is at least 80 to 100 mol % based on the overall acid quantity, the diol content at least 0 to 100 mol % of monoethylene glycol...
