• NAME: CTPB

1. Introduction
Carboxyl-terminated liquid polybutadiene rubber is generally called CTPB for short. For there are carboxyl at both ends of the polymeric molecule, this polymer carries on the structurization along the carboxyl group, the distribution of the network is neat and without any free terminal, so it has
