In this article, MWNTs were modified by three methods: by oxidizing the tubes and opening both ends, by filling with Ag, and by grafting with hexamethylene diamine
. The effects of the modification and interfacial interaction between the modified nanotubes and epoxy matrix on the dielectric behavior and mechanical properties were investigated.
Ethacure 420 from Albemarle Corp., Baton Rouge, La., is an aromatic diamine
that can be used with other products of this type (such as Albemarle's Ethacure 100) to add cure-time flexibility.
The polyamide is produced by the polycondensation of a diamine
component containing 70 mol % or higher of mxylylenediamine and a dicarboxylic acid component containing 70 mol % or higher of a C4-C20 [alpha],[omega]-linear aliphatic dicarboxylic acid, or comprising at least one layer made of the polyamide resin composition.
Evonik Industries will begin construction of production plants for the manufacture of isophorone and isophorone diamine
in the Shanghai Chemical Industry Park (SLIP), China.
In this study, we synthesized PUFs from 4,4'-diphenylmethane diisocyanate (PMDI) and polypropylene glycols (PPG), which were prepared from four different types of initiators such as sorbitol and its combinations with toluene diamine
(TDA), ethylene diamine
(EDA), and sucrose/ glycerin.
Developed by Chem Technologies, Advancure is said to be a low-cost curative for Vamac terpolymers that are cured with diamines
. The standard curative for Vamac compounds is hexamethylene diamine
Bulab 600, 685, and 693 tertiary amine catalysts based on TMEDA (tetramethyl-ethylene diamine
Consisting of polyester and polyether prepolymers produced from a specialty diphenylmethanediisocyanate, the Baytec MAC prepolymers demonstrate reactivities similar to those of corresponding, free-monomer stripped 2,4-TDI prepolymers when extended with diamine
coreactants such as MbOCA and MCDEA, thus achieving comparable physical properties, e.g., elastomeric, abrasion, and tear.
A blend of a hydrophobic additive and a nylon polymer includes a nylon other than a copolymer formed front a cyclic lactam and a C6-10 diamine
monomer or a C6-10 diacid monomer.
