cis‐polychloroprene

Abstract: cis‐Polychloroprene was synthesized by chlorinolysis of 1,4‐poly‐2‐(tri‐n‐butyltin)‐1,3‐butadiene. The latter was obtained by free radical polymerization of 2‐(tri‐n‐butyltin)‐1,3‐butadiene. The structure of cis‐polychloroprene was established by ozonolysis, and by infrared and NMR spectroscopy.

“…The relative intensity of olefinic proton signals at 6.7−5.8 ppm was 95:5, indicating that 95% and 5% of the cis and trans 1,4 structures, respectively, were included in the polymer. A similar tendency was observed in the free-radical polymerization of 1,3-dienes containing bulky substituents on the 2 position of the butadienyl skeleton such as 2-tributylstannyl-1,3-butadiene and 2-triisopropoxysilyl-1,3-butadiene . In either case, the steric hindrance might have controlled the microstructure as pointed out in a literature…”

“…231 It should be noted that there is one report of cis-polychloroprene but it was synthesised via post-polymerisation modification and not thoroughly characterised. 237 1,4-Polybutadiene (PB) is the unsubstituted analogue to PI and the absence of the methyl group yields a softer polymer and lower T g affording a material with a wider operating temperature range than polyisoprene. PB (from 1,3-butadiene) was first synthesised in a stereo-controlled manner using Zeigler-Natta type catalysts (transition metal and lanthanide complexes) and metal based catalysts continue to remain useful today.…”

“…79 Organotin-containing polymers, 23, have been made from 2-tributyltin-1,3-butadiene. 92 The polymerization is slow, but using a bulk process and azo-bis-isobutyronitrile at 60ºC, a clear colorless liquid product is formed after about 24 days.…”
