Catalytic synthesis of styryl-capped isotactic polypropylenes

Bis-styrenic molecules, 1,4-divinylbenzene (DVB) and 1,2-bis(4-vinylphenyl) ethane (BVPE), were successfully combined with hydrogen (H2) to form consecutive chain transfer complexes in propylene polymerization mediated by an isospecific metallocene catalyst (i.e., rac-dimethylsilylbis(2-methyl-4- phenylindenyl)zirconium dichloride, I) activated with methylaluminoxane (MAO), rendering a catalytic access to styryl-capped isotactic polypropylenes (i-PP). The chain transfer reaction took place in a unique way where prior to the ultimate chain transfer DVB/H2 or BVPE/H2 caused a copolymerizationlike reaction leading to the formation of main chain benzene rings. A preemptive polymer chain reinsertion was deduced after the consecutive actions of DVB/H2 or BVPE/H2, which gave the styryl-terminated polymer chain alongside a metal-hydride active species. It was confirmed that the chain reinsertion occurred in a regio-irregular 1,2-fashion, which contrasted with a normal 2,1-insertion of styrene monomer and ensured subsequent continuous propylene insertions, directing the polymerization to repeated DVB or BVPE incorporations inside polymer chain. Only as a competitive reaction, the insertion of propylene into metal-hydride site broke the chain propagation resumption process while completed the chain transfer process by releasing the styryl-terminated polymer chain. BVPE was found with much higher chain transfer efficiency than DVB, which was attributed to its non-conjugated structure with much divided styrene moieties resulting in higher polymerization reactivity but lower chain reinsertion tendency.

Synthetic method of 1,2-bis(4-vinylphenyl)ethane

The invention relates to a synthetic method of an organic intermediate, in particular to a synthetic method of 1,2-bis(4-vinylphenyl)ethane. A phase transfer catalysis method is adopted, p-chloromethyl styrene, copper powder and iron powder are used as raw materials, water and methylbenzene are used as solvents, and a phase transfer catalyst is added to synthesize the 1,2-bis(4-vinylphenyl)ethane.According to the synthetic method, the risk in the production process is low, the yield is improved, side reactions are reduced, and a high-quality product is obtained.
