Description

technical field

[0001] The invention relates to the field of plastic additives in the chemical industry, in particular to a thermally stable brominated aliphatic olefin / vinyl aromatic copolymer flame retardant and a preparation method for such a brominated aliphatic olefin / vinyl aromatic copolymer . Background technique

[0002] Hexabromocyclododecane (HBCD) is a general-purpose flame retardant (FR) and has a wide range of applications in the field of flame retardancy. However, studies have found that HBCD bioaccumulates in one or more species, is toxic to aquatic plants, and has persistent environmental effects on humans. This requires certain laws and regulations to limit and control the use of HBCD to reduce its impact on the environment and organisms. At the same time, it is very important to find a flame retardant that does not accumulate in organisms and has a low impact on the environment.

[0003] Due to the non-absorption of polymers by organisms and the low mobi...
