  • Halogen-free sulphonic acid ester and/or sulphinic acid ester as flame retardant, flame retardant synergists and radical generators in plastics
    Patent number: 11760865
    Abstract: The present invention relates to the use of halogen-free sulphonic acid esters and/or sulphinic acid esters as flame retardant and/or flame retardant synergists in plastics. The invention furthermore relates to the use of said compounds as radical generators in plastics, particularly in order to increase the molecular weight of the plastics, to branch and/or cross-link the plastics, to reduce the molecular weight of the plastics, to influence the molecular weight distribution of the plastics and to graft unsaturated monomers to the plastics. The present invention furthermore relates to the use of flame-retardant plastic compositions in the electrical or electronics industry, construction industry, transport industry, preferably automobiles, aircraft, trains and ships, for medical applications, for household appliances, vehicle parts, consumer products, packaging, furniture and textiles.
