Catalytic production of olefin block copolymers via chain shuttling polymerization.
We report a catalytic system that produces olefin block copolymers with alternating semicrystalline and amorphous segments, achieved by varying the ratio of alpha-olefin to ethylene in the two types of blocks. The system uses a chain shuttling agent to transfer growing chains between two distinct catalysts with different monomer selectivities in a single polymerization reactor. The block copoly...
متن کاملUnexpected reactivities of T cells selected by a single MHC-peptide ligand.
In H2-DM mutant mice, most MHC class II molecules are bound by a single peptide, CLIP, derived from the class II-associated invariant chain. Previous studies showed that H2-DM- cells are defective in presenting synthetic peptides to class II-restricted T cells. In sharp contrast, however, the same peptides elicited strong CD4+ T cell responses in H2-DM- animals. We now provide an explanation fo...
متن کاملNeutron Contamination Unexpected Dose in Varian LINAC
Introduction: Neutron contamination is very harmful for the patients receiving radiation therapy due to the high relative biological effect of neutrons. Medical linear accelerators head are made up of materials with high atomic numbers, and High-energy photons interaction with heavy materials can produce neutron contamination. In this study, neutron equivalent dose, neutron spe...
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 کاملReActivities ©: autism and play
ReActivities© are digital play sequences which encourage the integration of social, emotional and cognitive development in children on the autistic spectrum. Funding from the National Endowment for Science, Technology and the Arts (NESTA), Learning Programme, has enabled a collaborative approach to the development of the ReActivities© software. As a result of working directly with children on t...
