| 摘要 |
Liquid bromine-terminated polymers are directly prepared as by polymerizing one or more acrylates, acrylates in combination with isoprene, or butadiene with acrylonitrile using a combination of ultra-violet light and a dibromo-dichloro alkane containing at least two carbon atoms only as the polymerization initiator. These polymers are vulcanized with polyfunctional amines as curing agents to form solid elastomers, and are useful as base polymers for caulks, sealants, potting compounds, and like formulations.
