Polyethylene is the most widely used plastic in the world. The properties of polyethylene can be modified and enhanced by copolymerization with higher
?-olefines. The most important ones are butene (C4),
hexene (C6), and octene (C8). Ethylene can also be copolymerized with a wide range of non-olefinic monomers. Common examples are ethylene-vinyl-acetate copolymer (EVA) and different ethylene-acrylate copolymers. A method to increase the flame retardancy of polyolefines is the addition of nitrogen compounds (e.g. melamine, melamine-cyanurate, trihydrazinotriazine, etc.) 1, 2. In most of these well-known applications the nitrogen compound
is added after the polymerization of the olefin. However, at this stage problems occur due to this processing (e.g.melamine partly migrates to the surface; melamine-cyanurate tends to sublime and foam the polymer; etc.).
To avoid the mentioned problems, we have tried to incorporate a melamine based flame retardant via copolymerization, thus affording a hemically homogenous system. For the copolymerization we used pemtamethylmonovinylmelamine (PMMv), tetramethyldiv
inylmelamine (TMMvv), and trimethyltrivinylmelamine
(TriMMvvv)
