An Associative Pathway Enables Highly Controlled Ring‐Opening Polymerization of Cyclosiloxane with ppm‐Level Organocatalyst

ABSTRACT Precise control over molar mass and structure of polysiloxane is critical for its applications. Here, we report ring‐opening polymerization (ROP) of cyclotrisiloxane using anionized 1,3‐diphenylurea (UA1) as the catalyst. With a bulky tetra‐ n ‐butylammonium counterion,...
