摘要:The invention relates to a process for the synthesis of a Ziegler Natta procatalyst, the process comprising first treating magnesium alkoxide with a twice used mixed solvent of TiCl 4 and chlorobenzene to form a first stage product, then treating the first stage product with a once used mixed solvent of TiCl 4 and chlorobenzene to form a second stage product and finally treating the second stage product with mixed solvent recovered by treatment of effluent from the first treatment with benzoyl chloride so as to convert contaminant of formula TiCl 3 OR in the effluent to an addition complex which is precipitated, filtered off and hydrolyzed to recover ethyl benzoate and to form Ti(OH) 4 as a side product, the product after final treatment being subjected to a plurality of successive washing steps with used as well as recovered hexane.

标题:Synthesis of energetic polyester thermoplastic homopolymers and energetic thermoplastic elastomers formed therefrom

摘要:Polymerization of α-bromomethyl-α-methyl-β-propiolactone (BMMPL) or α-chloromethyl-α-methyl-β-propiolactone (CMMPL) yielded thermoplastic homopolymers that upon azidation led to a novel energetic thermoplastic polyester: poly(α-azidomethyl-α-methyl-β-propiolactone) (PAMMPL). An energetic copolyether-ester thermoplastic elastomer was prepared by using glycidyl azide polymer, a dihydroxyl terminated energetic polymer, as a macroinitiator for the polymerization of BMMPL or CMMPL. The azidation of the resulting copolyether-ester yielded an energetic thermoplastic elastomer that melted at between 80° C. and 85° C. Polymerization of α-dibromomethyl-β-propiolactone (DBMPL) resulted in a polymer which upon azidation yielded a new energetic polymer that can be used as a binder or into an energetic thermoplastic elastomer synthesis.
