WebNickel- and palladium-based catalyst systems were developed to convert 5-ethylidene-2-norbornene (ENB) to oligomers and polymers with highly controllable molecular weights. Depending on the choice of central metal ion, supporting ligand, and α-olefin chain transfer agent (CTA), ENB-derived materials ranging from dimers ( ca. 270 Da) to high molecular … Ethylidene norbornene (ENB) is an organic compound that consists of an ethylidene (CH3C(H)=) group attached to norbornene. It is a colorless liquid. The molecule consists of two sites of unsaturation. The compound consists of E- and Z-stereoisomers, but the mixtures are typically not separated.
Web1 de mar. de 2024 · Sample #12 (higher ENB content) has a lower molar mass than sample #11. The result in Fig. 17b is consistent with expectation, i.e., the ENB content decreased as the molar mass increased. Put differently, a blend of these two polymers was expected to produce an ENB content that varied along the MMD in the fashion observed in Fig. 17b.
