Abstract: The invention relates to ruxolitinib crystal and a pharmaceutical composition thereof. In particular, the invention provides ruxolitinib dihydrate crystal and a preparation method thereof, and ruxolitinib free base in amorphous form and a preparation method thereof, and a pharmaceutical composition comprising ruxolitinib dihydrate crystal or ruxolitinib free base in amorphous form. The crystal, amorphous form and pharmaceutical composition of the invention have simple preparation method, high product yield, and excellent crystal stability, hygroscopicity and processability, and thus are suitable for industrial production.

Abstract: The invention relates to functionalized bimodal butadiene-methylmethacrylate impact modifiers. The impact modifiers are especially useful in blends of engineering resins, particularly where the blend contains both functional and non-functional resins. Polycarbonate (PC)/polyethylene terephthalate (PET) blends using the functionalized bimodal butadiene-methylmethacrylate impact modifiers of the invention have excellent low temperature impact performance.

Abstract: The invention relates to a methylmethacrylate-butadiene-styrene (MBS) core/shell polymer impact modifier containing functionalization in the shell. The functionalized MBS is useful as an impact modifier in engineering resins, and especially in blends of engineering resins, particularly where the blend contains both functional and non-functional resins. One specific engineering resin blend having excellent low temperature impact performance is a polycarbonate (PC)/polyethylene terephthalate (PET) blend with the functional MBS of the present invention.

Abstract: The present invention relates to a toughened transparent thermoplastic composite of a transparent thermoplastic and a block copolymer having a block of a random copolymer and an elastomeric block. One preferred embodiment is a polycarbonate that is modified with a block copolymer having a methyl methacrylate (MMA) and naphthyl methacrylate or a substituted naphthyl methacrylate block and an elastomeric block. This block copolymer has excellent miscibility with polycarbonate resin, even at elevated temperature, producing transparent polycarbonate blends. The blend can provide a toughened strength polycarbonate while maintaining its excellent optical properties.

Abstract: The invention relates to a transparent thermoplastic blend of polycarbonate (PC) and a copolymer of methyl methacrylate (MMA) and naphthyl methacrylate or a substituted naphthyl methacrylate.

Abstract: The present invention relates to a thermoplastic/natural cellulosic fiber composite, and more specifically to a high molecular weight compatibilizer within that composite resulting in both a high flex strength and high modulus and significant reduction in water absorption. The compatibilizer is preferably a terpolymer comprising: a) 0.5-20 percent by weight of monomer units selected from the group consisting of maleic anhydride, substituted maleic anhydride, mono-ester of maleic anhydride, itaconic anhydride, maleic acid, fumaric acid, crotonic acid, acrylic acid and methacrylic acid; b) 0 to 40 percent by weight of monomer units selected from styrene and functionalized styrene; and c) 40 to 98.5 percent by weight of monomer units selected from the group consisting of C1-8 alkyl acrylates and methacrylates, and vinyl acetate.
