Embodiments are directed to catalyst systems comprising: a procatalyst; and a co-catalyst dissolved in a non-halogenated aprotic hydrocarbon solvent, the co-catalyst comprising: a non-coordinating borate dianion having the formula: (III) and two cations, each cation being independently chosen from a cation according to formula (I) or formula (II).

Highly soluble bis-borate as binuclear co-catalysts for olefin polymerization

Methods for forming polar-functionalized isotactic and syndiotactic polypropylenes are provided, including amino-functionalized polypropylene. In embodiments, such a method comprises contacting a propylene monomer and a polar monomer comprising an amine group in the presence of an organozirconium catalyst and in the absence of a masking reagent, under conditions to induce a polymerization reaction between the propylene and polar monomers, thereby forming polar-functionalized polypropylene.

Methods for forming stereospecific, polar functionalized polypropylene

Embodiments are directed to catalyst systems comprising: a procatalyst; and a co-catalyst, the co-catalyst comprising: a non-coordinating borate anion having the formula [B(CF)]and a cation according to formula (I).

Highly soluble alkyl substituted carbenium borate as co-catalysts for olefin polymerizations

Low molecular weight, highly branched polyolefins are provided. Also provided are catalyst-mediated methods of making the low molecular weight, highly branched polyolefins and a catalyst system for carrying out the methods. The catalyst system is a homogeneous catalytic system that includes a single-site organozirconium complex and hydrocarbon-soluble perfluoroarylborate co-catalyst that is highly active for the oligomerization of olefin monomers in non-polar media.

Highly branched, low molecular weight polyolefins and methods for their production

A method for forming polar-functionalized polyolefins may comprise contacting an unsubstituted &#x3b1;-olefin monomer and an amino-olefin monomer of formula HC&#x2550;CH(CH)(CHR)NR', wherein R is H or an unsubstituted linear or branched alkyl group having from 1 to 10 carbons, each R&#x2032; is an independently selected unsubstituted linear or branched alkyl group having from 1 to 10 carbons, m is an integer from 1 to 11, and n is an integer from 1 to 11, in the presence of a rare earth catalyst and a cocatalyst under conditions to induce a heteropolymerization reaction between the unsubstituted oc-olefin and amino-olefin monomers to provide a polar-functionalized poly olefin.

The organic semiconductor polymers relate to polymers containing an indolo-naphthyridine-6,13-dione thiophene (INDT) chromophore. The organic semiconductor polymers are formed by polymerizing INDT monomer with thiophene to obtain a conjugated polymer of the chromophore linked by thiophene monomers (INDT-T), with phenyl to obtain a conjugated polymer of the chromophore linked by phenyl monomers (INDT-P), with selenophene to obtain a conjugated polymer of the chromophore linked by selenophene monomers (INDT-S), or with benzothiadazole to obtain a conjugated polymer of the chromophore linked by benzothiadazole monomers (INDT-BT).

Organic semiconductor polymers

Van der Waals heterojunctions are extended to semiconducting p-type single-walled carbon nanotube (s-SWCNT) and n-type film that can be solution-processed with high spatial uniformity at the wafer scale. The resulting large-area, low-voltage p-n heterojunctions can exhibit anti-ambipolar transfer characteristics with high on/off ratios. The charge transport can be efficiently utilized in analog circuits such as frequency doublers and keying circuits that are widely used, for example, in telecommunication and wireless data transmission technologies.
