Compatibility improvement

Excellent compatibility Improves wet and dry crock Improves light fastness Excellent color yield Applicable on a variety of fabrics... 

Hahgenated polymers, both brominated and chlorinated, have been developed to yield better polymer compatibility, improve physical properties, and long-term-aging characteristics in many thermoplastic resins, particularly the high-performance engineering thermoplastics, such as nylon, polybutylene terephthalate (PBT) and polyethylene terephthalate (PET). These materials still use antimony oxide as a synergist to achieve the desired flame resistance (31).

Coupling agents are ehemieals that are used to treat the surface of fillers. These ehemieals normally have two parts one that combines with the surface ehemieaUy and another that is eompatible with the polymer. One example is the treatment of ealeium earbonate filler with stearic acid. The acid group of the latter reacts with the surface, whereas the ahphatic chain sticks out of the surface and is eompatible with the polymer matrix. In the same way, if carbon black is to be used as a filler, it is first mixed with benzoyl peroxide in alcohol at 45°C for at least 50 h and subsequently dried in vacuum at 11°C [5]. This activated carbon has been identified as having C—OH bonds, which can lead to polymerization of vinyl monomers. The polymer thus formed is chemically bound to the filler and would thus promote the compatibihzation of the filler with the polymer matrix. Most of the fillers are inorganic in nature, and the surface area per unit volume increases with size reduction. The number of sites where polymer chains can be bound increases, and, consequently, compatibility improves for small particles.
