In the same time frame, Carothers discovered neoprene, which was a chain-polymerized product of an isoprene-like monomer with a chlorine replacing the methyl group.Bakelite was thermoset; that is, it did not flow the synthesis was complete (20). The first synthetic thermoplastics, materials that could flow on heating, were poly(vinyl chloride), poly(styrene-stat-butadiene), polystyrene, and polyamide 66; see Table 1.8 (20). Other breakthrough polymer have included the very high modulus aromatic polyamides, known as Kevlar (see section 7.4)
