    摘要: The present invention discloses a method of dispersing cyclodextrins into a base polymer. The method of the invention comprises reacting grafted microfine polymer powder with a cyclodextrin to form a cyclodextrin-attached grafted polymer, and mixing the cyclodextrin-attached grafted polymer and the base polymer for a sufficient time that the cyclodextrin-attached grafted polymer is dispersed within the base polymer. The present invention also provides several cyclodextrin-inclusion complex products formed by the method of the invention. This products include an antimicrobial polymer blend, a fragrant polymer blend, and a dyed polymer blend.

    摘要: A multiple stage or multiple zone process for making olefin polymers is disclosed. A single-site catalyst, preferably one that contains a heteroatomic ligand, is used in the first stage or zone, and a Ziegler-Natta catalyst is used at a higher temperature in later stages or zones. A parallel multiple zone process is also described. The processes, which can be performed adiabatically, give polymers with improved thermal processing ability.

    摘要: A process for preparing boratabenzene derivatives is provided. The process includes the hydrogenation of a compound containing a boranaphthalene functional group to form a boratabenzene-containing compound. Depending on the compound containing a boranaphthalene functional group, the resulting boratabenzene compound may be converted into a catalyst suitable for olefin polymerization. A process for forming a boratabenzene derivative from a halo-dioxaborolane is also provided. In this process, a halo-dioxaborolane is reacted with a piperylide salt for form a pentadienyl dioxaborolane. The pentadienyl-dioxaborolane is reacted with a strong base to form an intermediate boratacyclohexanediene salt. The intermediate boratacyclohexanediene salt is then reacted with a trialkylaluminum compound to form an alkylboratabenzene salt.
