Abstract: A device for monitoring environmental exposure includes an element whose electrical properties change, in a predetermined way, in response to the environmental exposure. The element may be part of a tuned circuit or of a shield for a tuned circuit. In either case, when the tuned circuit is interrogated, preferably by an r.f. or microwave signal, it emits a signal whose intensity depends on the electrical properties of the element. Thus, an incremental environmental exposure can be measured by a change in the signal intensity. The device is particularly useful for monitoring the condition of perishable materials, because it can be located with the perishable inside a packaging material during both storage and interrogation.

Abstract: Conjugated backbone polymers (e.g., polyacetylene), especially formed into a battery electrode, are contacted with a compound MR where M is an alkali metal and R is alkyl of 1-12 carbons, phenyl or alkylphenyl of 7-12 carbons. The method is particularly suited to treatment of battery electrodes to avoid a high initial internal resistance.

Abstract: A polymer solution is formed from a sulfur- or oxygen-containing aromatic polymer solute such as poly(phenylene sulfide) or poly(phenylene oxide), a Lewis Acid solute derivative (dopant) such as arsenic hexafluoride and a strong acid solvent such as sulfuric acid. Solvents such as fluorosulfonic acid may also serve to generate the dopant. The solutions are especially useful for casting polymer articles.

Abstract: A recording device is described, useful as an integrated time-temperature or radiation-dosage history indicator. The device contains a substrate having deposited thereon at least two indicating units, one being unreacted and representing zero time of exposure and the other unit being pre-reacted. Each unit is comprised of an acetylenic compound containing at least one --C.tbd.C--C.tbd.C-- group, capable of reacting by 1,4-addition polymerization thereby forming an end-point color after an irreversible, progressive color change upon thermal annealing or exposure to actinic radiation. The end-point color represents an integrated time-temperature history of thermal annealing or radiation-dosage history. Each unit is constructed such that the time required to form the end-point color by thermal annealing at a given temperature or for a known thermal history, or exposure to actinic radiation at a given average radiation dosage rate, is predetermined.

These doped polymers have utility similar to semiconductors or to metals, particularly where light weight is desired, for example in battery electrodes.

Abstract: Certain polyacetylenes exhibit reversible color changes at transition temperatures in the range -180.degree. to 220.degree. C., wherein the thermochromic cycles can be repeated many times with no apparent degradation and little change in spectroscopic properties.These thermochromic polyacetylenes are useful in temperature-indicator and indicia-display device applications.A process for laser-beam recording of images is described employing a thermochromic polyacetylene, in which the hysteresis properties of the polyacetylene can be suitably altered allowing for selectively storing or erasing the formed image.
