Glass transition temperatures of poly(alkyl α‐cyanoacrylates). Since ethyl cyanoacrylate polymerizes rapidly on contact with moisture, volatilization from moist soil surfaces is not a relevant environmental process for this substance. The chemistry of cyanoacrylate polymerization process is well known (Woods et al. Cyanoacrylates are commercially important monomers used for rapid-curing structural adhesives. The glue works through a polymerization reaction, in which molecules of methyl cyanoacrylate form strong chemical bonds to one another and to the surfaces being glued. A research student working under Coover synthesised ethyl cyanoacrylate, and, in trying to measure the compound’s refractive index, accidentally stuck two glass prisms together. Due to the slow, in situ formation of the cyanoacrylate monomers, the polymerization is easier and better to be controlled than a direct ionic polymerization. Poly(methyl methacrylate)-block-poly(n-butyl acrylate)-block-poly(methyl methacrylate) triblock copolymers (MnBM) have been synthesized by the sequential controlled radical polymerization (atom transfer radical polymerization, ATRP) of n-butyl acrylate (n-BuA) followed by methyl methacrylate (MMA).

The basic chemical reactions for the formation of the methyl .alpha.-cyanoacrylate can be represented by the equations: ##STR1## The depolymerization yields the desired methyl cyanoacrylate, and methyl cyanoacetate. Generally, ethyl cyanoacrylate forms stronger, more durable joints to rubber and other flexible substrates; methyl cyanoacrylate adhesives produce slightly higher joint strengths with rigid plastics and metals [1, 3, 7, 14]. It is difficult to separate methyl cyanoacrylate from methyl cyanoacetate by distillation because the boiling points fall close together.
