Catalyst Resin Beads with Intermediate Crosslinking

The patent changes the crosslinking level parameter to an intermediate range (5-15%) rather than using traditional low crosslinking for gel resins or high crosslinking for macroporous resins. This parameter optimization resolves the contradiction by achieving both adequate catalytic effectiveness and improved physical toughness, as demonstrated by the resin's ability to maintain structural integrity while providing sufficient active sites for catalysis.

The patent creates a composite resin structure combining characteristics of both gel and macroporous resins. The resin incorporates a controlled crosslinking density that produces an intermediate pore structure, effectively combining the high catalytic activity of gel resins with the physical robustness of macroporous resins, thereby resolving the trade-off between these two properties.

The patent optimizes the crosslinking level parameter to an intermediate range (5-15%), avoiding the excessively high crosslinking of traditional macroporous resins. This parameter adjustment maintains sufficient physical toughness while preventing over-crosslinking from blocking pores and reducing catalytic effectiveness, thus resolving the contradiction.

The patent creates local variations in crosslinking density within the resin structure, providing regions of higher crosslinking for physical strength and regions of lower crosslinking for catalytic activity. This local quality differentiation allows the resin to simultaneously exhibit both physical toughness and catalytic effectiveness.
