application: I'm trying to create a substance that could be used by people in a "high height" environment (rock climbers, construction workers, window wipers, etc.) as a sort of "instant safety rope".
in essence, if someone in a high position (such as a construction worker on a high-rise apartment project for example) was to fall without a secure fasten to something, they could activate a device (I'm still sketching out the prototype for that) that would unleash this substance /polymer from an air tight (pressurized?) container. The substance in question would solidify as it exited the chamber, and seeing as more is being forced out from behind it, it would grow rapidly in length. It would then stick to whatever surface it had been aimed at, and in short save whoever was using it from a sure and definite demise.
I'm still worried about wether or not a substance could be created that would be capable of resisting the strain that this "rope" would undoubtedly have to endure (the weight of whoever was using it + the force applied by how far they have fallen). So far, polymers have seemed to be my best bet for this sort of substance (become solid and rope-like when forced through an opening, etc.) but issues with melting points in relation to ambient outdoor temperature, how it could stick to a variety of surfaces relatively quickly and hold strong under immense pressure, and wether or not enough of this material to form a sturdy lifeline could be placed in a transportable and unobtrusive (e.g. not a giant backpack) container..
