Monomer reactivity ratios^a of co-monomers (M₁) and DMDL (M₂) determined by the Fineman–Ross method.

Entry	M 1	T (°C)	r 1 a	r 2 a
1	MMA	60	4.60	Close to zero
2	BA	60	0.83	0.03b
3	St	80	1.08	0.01b
4	AN	70	0.28	0.04b
5	VAc	70	1.65	0.29

^a r ₁ = r₁₂/r₁₁ and r₂ = r₂₁/r₂₂.

^b r _DMDL = 0–0.10 with an experimental error.
