Prepn. of dynamically cured polyolefin thermoplastic elastomers (all pts.wt.): 20-80 crystalline olefin polymer, 80-20 butadiene and/or isoprene contg. elastomer, in this case with other polymers, grafting monomers, fillers structuring agents additives or mixtures thereof and 2-20 phenolic resin and a metal cpd., in this case a halogen donor. - The elastomer is thermoplastic, inexpensive, is easily compatible with elastomers used in the shoe-industry, is suitable to improve the impact resistance polystyrene homo and copolymers and the compatibility of constituents in polyolefin, polystyrene and polyolefin, polystyrene, PVC mixes. It facilitates the reuse of these. The process is suitable for the prod. of ensured quality secondary raw materials from wastes. |
