Hydrothermal synthesisPoly(paraphenylenediamine)/niobium oxide core–shell composite microspheres have been hydrothermally synthesized using the niobium oxide Nb2O5 as inorganic precursor and paraphenylendiamine as a structure-directing agent. Such techniques as X-ray diffraction (XRD), scanning electron ...
para -Phenylenediamine was polymerized with terephthalic acid in SO 3 at 20–47% polymer concentration to form highly anisotropic (liquid crystalline) sulfonated poly( p -phenyleneterephthalamide) (SPT) solutions (dopes) with inherent ... FM Silver - 《Journal of Polymer Science Polymer Chemistry...
This paper introduces the preparation and performance of a novel high performance pulp, poly(p-benzamide)(PBA) pulp, which has bigger specific area and excellent heat-resistance than para-phenylene terephthalamide(PPTA) pulp. 介绍了一种新型高性能浆粕——聚对苯酰胺(PBA)浆粕的制备和性能。2...
(a) Identity. For the purpose of this section, the poly(phenylene- terephthalamide) resins (CAS Reg. No. 26125-61-1) are produced by the polymerization of terephthalolyl chloride with p -phenylenediamine. The poly(phenyleneterephthalamide) resin fibers and yarns may contain optional adjuvant...
The reaction of terephthalic acid (TA) and para-phenylenediamine sulfate (PPD-S) in sulfur trioxide to form anisotropic, sulfonated poly(p-phenyleneterephthalamide) (SPT) dopes was reported in Part IV of this series. We have found now th... FM Silver - 《Journal of Polymer Science Polymer...

1.5 parts of N-Isopropyl-N'-phenyl-p-phenylenediamine (IPPD) per 100 parts of natural rubber in each compound. Moreover it was found that during the accelerated thermal aging of vulcanizates post-curing effect occurs. This phe- nomena is connected with increasing of cross-link density and ...
via a condensation process between para-phenylenediamine (PD) and meso-tetrakis (p-carboxyphenyl) porphyrin (TCPP) (Fig. 9a). Por-PD-COF’s large surface area, plenty of active sites, and strong stability allow it to swiftly and effectively absorb methylene blue (MB) and extract it from ...
EXPERIMENTAL Materials p-Phenylenediamine (IIIa; from Tokyo Chemical Industry, TCI) and m-phenylenediamine (IIIb; from TCI) were vacuum-distilled before use. Other diamines including 2,4- diaminotoluene (IIIc; from TCI), 4,4 - oxydianiline (IIId; from TCI), 4,4 -methylenedianiline (IIIe; ...
