Abstract:
The invention relates to degradable chewing gum polymer, said degradable polymer is a polymer polymerized from at least one trifunctional or higher functional initiator, at least two different monomers forming the backbone of the polymer and at least one monomer selected from the group of carbonate monomers. According to the invention it has been realized that a certain degree of branching of the backbone is needed to obtain a final improved performance, when the polymer, preferably the elastomer, is incorporated in a chewing gum. It has moreover been realized that the obtained degree of branching needs and may actually be carefully controlled in order to avoid too much branching-induced crosslinking.
Abstract:
Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with an N-substituted pyrrole to thereby functionalize the N-substituted pyrrole at the terminal reactive polymer chain end(s). Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is subsitituted at the 2 and 3 position of the N-substituted pyrrole.
Abstract:
The present invention is directed to a method for preparation of polyolefins containing exo-olefin chain ends. The method involves quenching a cationic quasi-living polyolefin polymer system with one or more hindered secondary or tertiary amines.
Abstract:
The present invention is directed to a method for preparing polyolefins containing a high percentage of exo-olefin chain ends. The method involves ionizing a polyolefin containing tert-chloride chain ends and reacting the ionized polyolefin with one or more nitrogen-containing five-membered aromatic ring or one or more hindered secondary or tertiary amines, or mixtures thereof.
Abstract:
Disclosed is a method for preparing polyolefins containing vinylidine end groups from quasiliving carbocationically terminated polyolefin polymers by contacting the quasiliving carbocationically terminated polymer with a suitable azole quenching agent and substituted derivatives thereof.
