EPOXY ACRYLIC/ACRYLIC/EPOXY ACRYLIC BLOCK COPOLYMERS

ABA triblock polymers that have glycidyl methacrylate (GMA) as the A segments and standard (meth)acrylate monomers as the B segment are made by group transfer polymerization, using a monofunctional initiator to make the A, then AB, then ABA segments, or a difunctional initiator to make the B then AB...

Beschreibung
Zusammenfassung:	ABA triblock polymers that have glycidyl methacrylate (GMA) as the A segments and standard (meth)acrylate monomers as the B segment are made by group transfer polymerization, using a monofunctional initiator to make the A, then AB, then ABA segments, or a difunctional initiator to make the B then ABA segments. Alternatively, a coupling agent can be used to connect AB segments at the B group after a monofunctional initiator reacts A and B or an epoxy-containing initiator reacts with a B segment.
