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. WebPolymer. Product Subtype EPDM.
