An alpha-halocarbo aromatic monomer or comonomer and/or an allyl halide monomer or comonomer can be reacted with aluminum or an aluminum-containing catalyst to form a polymer.

Polymer

Sensor switch includes a compromisable mechanical restrainer and a biased member. Before compromise, the restrainer can hold the biased member in a first position. When contacted with a target chemical and/or composition, the restrainer is physically compromised by being softened or dissolved such that the biased member can assume a second position different from the first position. Monitoring a sample for a target chemical and/or composition can be carried out with the sensor switch.
