Abstract
The removal of mercaptans from polymer compositions is described, where removal occurs by at least one of: contacting the polymer composition with a radical initiator that reacts with the mercaptain compound to form a non-odorous compound; and contacting the polymer composition with a transition metal that immobilizes the mercaptan compound.
Claims26
A method for removing a mercaptan compound present in a polymer composition, comprising at least one of:
- contacting the polymer composition with a radical initiator that reacts with the mercaptan compound to form a non-odorous compound;
- and
- contacting the polymer composition with a transition metal that immobilizes the mercaptan compound.
A method for deodorizing a mercaptan odor from a polymer composition, comprising at least one of:
- contacting the polymer composition with a radical initiator that reacts with a mercaptan compound to form a non-odorous compound;
- and
- contacting the polymer composition and a transition metal that immobilizes a mercaptan compound.
