Coordination Copolymerization of Polar Vinyl Monomers H2C[double bond]CHX
Of all polymerization methods, catalytic polymerization offers the broadest scope of microstructure control. Stereoregularity, comonomer incorporation and sequences, molecular weights, and molecular weight distributions can be controlled by the catalyst structure. Polyolefins are produced on a vast scale of nearly 100 million tons annually, predominantly by catalytic polymerization. High-densit...
متن کاملEthyl 4,6-O-benzylidene-2-deoxy-N-phthalimido-1-thio-β-d-glucopyranoside
In the title compound, C(23)H(23)NO(6)S, the plane of the N-phthalimido group makes a dihedral angle of 67.4 (1)° with the least square plane of the sugar ring defined by the C2, C3, C5 and O5 atoms using standard glucose nomenclature. The thio-ethyl group has the exo-anomeric conformation. In the crystal, inter-molecular hydrogen bonds involving the hy-droxy groups and the carbonyl O atoms of ...
متن کاملEthyl 3,6-di-O-benzyl-2-deoxy-N-phthalimido-1-thio-β-d-glucopyranoside
In the title compound, C(30)H(31)NO(6)S, the plane of the N-phthalimido group is nearly orthogonal to the least-squares plane of the sugar ring (defined by atoms C2, C3, C5 and O5 using standard glucose nomenclature), making a dihedral angle of 72.8 (1)°. The thio-ethyl group has the exo-anomeric conformation. The hy-droxy group forms an inter-molecular hydrogen bond to the O atom in the sugar ...
متن کاملRelative Reactivities in Vinyl Copolymerization
Synopsis. From data in the literature on relatine rates of copolymerization it has been possible to evaluute two constants, Q and e , cheracteristic of a n individual monomer, which appear to account satisfactorily .for its behavior in copolymerization. The constant Q describes the “general monomer reactivity” and is apparently related to possibilities for stabilization in a radical adduct. The...
متن کاملTri-n-Butylborane/WaterComplex-Mediated Copolymerization of Methyl Methacrylate with Proteinaceous Materials and Proteins: A Review
Previous studies of tri-n-butylborane–initiated graft copolymerization of methyl methacrylates with hydrated proteinous materials and proteins have focused on the number of grafted-poly (MMA) branches as well as the percent graft and graft efficiency. The number of branches in silk fibroin is 1.3, whereas the number in collagen, gelatin, ovalbumin and wool are 0.1, 0.04, 0.02 and 0.03, respecti...
