在一般情况下，头至尾除了被认为是在所有聚合的主要传播方式。然而，当单体取代小（不提供可观的空间位阻接近激进）或不具备中氟原子的情况下，头 - 头繁殖相当大的共振稳定作用，可能会发生。提高聚合温度的影响是增加量头头部位置。温度升高，导致选择性（随机）传播，但效果并不大。因此，在聚头 - 头（醋酸乙烯）含量增加表格1.30％至1.98％时，聚合温度在30℃提高到90℃

In general, head-to-tail addition is considered to be the predominant mode of propagation in all polymerizations. However, when the substituents on the monomer are small (and do not offer appreciable steric hindrance to the approaching radical) or do not have a large resonance stabilizing effect, as
