  "description": "<p>Norbornene is polymerized extremely fast when reacted with Grubbs&rsquo; first (<strong>G1</strong>) or third generation catalyst (<strong>G3</strong>) because of its very high ring strain energy. Cyclohexene, on the other hand, cannot be polymerized using <strong>G1</strong> or <strong>G3</strong> due to its very low ring strain energy. Subsequently, the sequence-selective polymerization of these two monomers is extremely challenging. A sequence-selective cascade ring-opening/ring-closing metathesis polymerization of the monomer <strong>M</strong> containing both the norbornene and the cyclohexene ring using <strong>G1</strong> or <strong>G3</strong> is reported. The polymer structure was analyzed by <sup>1</sup>H NMR, <sup>1</sup>H&ndash;<sup>1</sup>H COSY, and <sup>1</sup>H&ndash;<sup>1</sup>H ROESY spectroscopy and MALDI-ToF mass spectrometry. Polymers with moderate molecular weight dispersities and good molecular weight control were achieved by varying the ratio between monomer <strong>M</strong> and <strong>G1</strong>.</p>",
