polysulfide polymer

polysulfide polymer

[pol′ēsul′fīd]
an elastomeric synthetic rubber used in dentistry as an impression material for fixed partial prosthodontic structures, inlays for single quadrants, and dental impressions. Also called polysulfide rubber.

polysulfide polymer (pol´ēsul´fīd pol´imur),

n a rubber base impression material that makes use of a mercaptan bondage. It is prepared by mixing a base material (mercaptan) with either an inorganic catalyst (lead peroxide) or an organic catalyst (benzoyl peroxide).

Polysulfide polymer is cured by converting mercaptan (-SN) groups to disulfide (-S-S-) bonds.
Polysulfide polymer is cured by converting mercaptan(-SH) end groups to disulfide (-S-S-)bonds.
Liquid polysulfide polymers, such as the Thiokol LP series (Morton International), are also able to form reactive crosslinking short chains through accelerator peptization of the sulfurs in the polymer chain.
