通过3-环戊烯基α-溴异丁酸酯的变温开环易位聚合来合成聚戊烯大分子引发剂，其具有足够的环应变（ΔHp = -22.6 kJ mol-1）以产生目标摩尔质量（1000 kg mol-1）和ε = 1.33。该系统具有高度的合成通用性和控制性，具有独特的柔性主链，以扩展密集接枝聚合物的套件。
Polypentenamer macroinitiators are synthesized through variable temperature ring opening metathesis polymerization of 3-cyclopentenyl α-bromoisobutyrate, which has sufficient ring strain (ΔHp = -22.6 kJ mol-1) to produce targeted molar mass (1000 kg mol-1) and Đ = 1.33. This system exhibits high synthetic versatility and control with a unique flexible backbone to expand the suite of densely grafted polymers.
