Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article presents a comprehensive study on the use of potassium diphenylphosphide (KPPh2) as a highly efficient initiator for the anionic ring-opening polymerization (ROP) of epoxides. Unlike traditional initiators, KPPh2 exhibits superior nucleophilicity, enabling rapid and controlled polymerization of glycidyl phenyl ether (GPE) without the need for additives. The resulting polymers display high molecular weights and narrow molecular weight distributions. Additionally, KPPh2 demonstrates exceptional catalytic ability in the addition of phenols to epoxides, showcasing its potential for applications in epoxy-phenol curing systems. The study provides valuable insights into the mechanisms of phosphide-initiated polymerization and addition reactions, paving the way for the development of new rapid-curing systems for epoxy resins.
