Novel soluble polyimides having long-chain alkyl groups on their side chain were synthesized via polymer reaction with the polyimides having phenolic OH groups and 3,4,5-tris(dodecyloxy)benzoic acid (12GA) using N,N???-dicyclohexylcarbodiimide (DCC) as a dehydration reagent. The polyimides ...
The present invention relates to a process for the manufacture of a crosslinked polymer, wherein a crosslinking reaction is carried out between an organic crosslinking agent which is a polyacid or a derivative of a polyacid, and a long chain alkylpolyamine having at least two amine functional...
PROBLEM TO BE SOLVED: To provide a high-purity long-chain alkyl group-containing diol having the long-chain alkyl groups in a pendant form and two primary hydroxy groups, to further provide a method for producing the long-chain alkyl group-containing diol by polyaddition with a polyisocyanate ...
which generally related to and limited by the carrier's solubility, works for polymer-supported catalysts modifications often focused on co-polymerizing soluble materials [19], [20], [21], [22] such as polyethylene glycol (PEG) or crown-ethers, while long alkyl chain addition normally acted ...
When the length of the alkyl chain was longer than -C16H33, the polymer solidified with higher melting points than at room temperature. The poly(trimethylene carbonate) (PTMC) derivative with a -C18H37 group at the side chain was used for the hydrolysis test both in organic and aqueous ...
