Moisture-curable rubbers, 4†. Moisture-cure of chloroprene rubber
Part 3: cf.4.
Abstract
Chloroprene rubber (CR) was allowed to react with 3-aminopropyltriethoxysilane (APS) and then cured by soaking in hot water. The moisture-cured rubber showed a network-chain density of 3,6·10−4 mol·cm−3 and a tensile strength at break of 10 MPa. The reaction of CR with APS was found to be a Menshutkin reaction. The activation energy and the frequency factor were 59 kJ·mol−1 and 4,3·104 l·mol−1·s−1, respectively.
