摘要:The invention relates to a new process for the manufacture or synthesis, respectively, of fluorinated benzenes and fluorinated benzophenones, and derivatives thereof, in particular of fluorobenzenes and derivatives thereof. The present invention particularly pertains to a novel environmentally friendly process for the synthesis of fluorinated benzenes and benzophenones as raw materials for the manufacture of polyaryletherketones (PAEKs).

摘要:A method for forming a polyaryletherketone is described. More particularly, a reaction mixture is initially supplied to the reactor vessel that contains one or more precursor monomers. A heteroaryl compound is also added to the reaction mixture. The reaction can be carried out according to, e.g., an electrophilic aromatic substitution reaction or a nucleophilic aromatic substitution reaction. The heteroaryl compound can serve as a dispersant to the polymer as it is formed. This minimizes the likelihood of gelling of the product polymer within the reactor vessel and limits the impact of process disruptions on the production of the polyaryletherketone.

摘要:Described herein are PEKK polymers having improved processability and improved crystallinity. It was surprisingly found that PEKK polymers formed using a specifically adapted nucleophilic synthesis route, in which different monomers are added in to the polymerization reaction at different points during the synthesis, had lower glass transition temperatures (“Tgâ€?) and increased crystallinities, relative to PEKK polymers formed using traditional nucleophilic synthesis routes (“traditional PEKK polymersâ€?). Furthermore, compared with PEKK polymers synthesized using an electrophilic synthesis routes, the PEKK polymers described herein and significantly lower halogen content. The synthesis routes includes a first heating of a first monomer blend in a reaction mixture, a subsequent first addition of a second monomer blend to the reaction mixture, and a second heating of the reaction mixture subsequent to the first addition.

摘要:Described herein are PEKK polymers having improved processability and improved crystallinity. It was surprisingly found that PEKK polymers formed using a specifically adapted nucleophilic synthesis route, in which different monomers are added to the polymerization reaction at different points during the synthesis, had lower glass transition temperatures ('Tg') and increased crystallinities, relative to PEKK polymers formed using traditional nucleophilic synthesis routes ('traditional PEKK polymers'). Furthermore, compared with PEKK polymers synthesized using an electrophilic synthesis routes, the PEKK polymers described herein and significantly lower halogen content. The synthesis routes includes a first heating of a first monomer blend in a reaction mixture, a subsequent first addition of a second monomer blend to the reaction mixture, and a second heating of the reaction mixture subsequent to the first addition.

摘要:Described herein are poly(ether ketone ketone) (“PEKKâ€?) polymers having improved processability. It was surprisingly discovered that by selectively controlling the relative amounts of reactants during the synthesis, PEKK polymers having unexpectedly lower melt viscosities can be obtained. More particularly, by selectively controlling the relative amounts of monomers used to form recurring units of the PEKK polymer, in conjunction with selective control of other reaction components, the resulting PEKK polymers had reduced viscosities, relative to PEKK polymers synthesized by using tradition reaction schemes (“traditional PEKK polymersâ€?). By providing PEKK polymers with lower melt viscosities, the PEKK polymers described herein have improved processability.
