Pei Bian* and Thomas J. McCarthy* recently published a paper in ACS Macro Letters entitled, Hemisilicone Elastomers that are Recyclable to the Monomer. In this research, the linear polymer, –(SiMe2–O–SiMe2–CH2CH2)n–, which can be regarded as an alternating copolymer of the dimethylsilicone unit, M–M and ethylene, was used in place of polydimethylsiloxane to prepare 2-part curable silicones.
