Disclosed are conjugated polymers having desirable properties as semiconducting materials. Such polymers are cheap and easy to synthesize, and can exhibit good solubility and great solution processibility, and that enable highly efficient OPVs.

Cathodes for a fast charging lithium ion battery, processes for manufacturing thereof and corresponding batteries are provided. Cathode formulations comprise cathode material having an olivine-based structure, binder material, and monomer material selected to polymerize into a conductive polymer upon partial delithiation of the cathode material during at least a first charging cycle of a cell having a cathode made of the cathode formulation. When the cathode is used in a battery, polymerization is induced in-situ (in-cell) during first charging cycle(s) of the battery to provide a polymer matrix which is evenly dispersed throughout the cathode.

There is provided an electroactive material having Formula I

##STR00001##

wherein: Q is the same or different at each occurrence and can be O, S, Se, Te, NR, SO, SO.sub.2, or SiR.sub.3; R is the same or different at each occurrence and can be hydrogen, alkyl, aryl, alkenyl, or alkynyl; and R.sup.1 through R.sup.6 are the same or different and can be hydrogen, alkyl, aryl, halogen, hydroxyl, aryloxy, alkoxy, alkenyl, alkynyl, amino, alkylthio, phosphino, silyl, —COR, —COOR, —PO.sub.3R.sub.2, —OPO.sub.3R.sub.2, or CN.

Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.
