摘要: Chloroalkylthiolcarbamate compounds of the formula: ##STR1## wherein Z represents ##STR2## and when Z is ##STR3## n is an integer of 4 to 10, whereas when Z is ##STR4## n is an integer of 3 to 10. These compounds are useful as effective herbicides having no harmful effect on the ecosystem, particularly extremely low toxicity to fish, and can be obtained, for example, by reacting the corresponding thiolcarbamate derivatives with a chloroalkyl halide.

摘要: Thermoplastic elastomers of conjugated diolefins having 4 to 6 carbon atoms and monovinyl aromatic hydrocarbons are prepared by polymerizing 8 to 65 parts by weight of a monomer mixture A.sub.1 comprising a conjugated diolefin having 4 to 6 carbon atoms and a monovinyl aromatic hydrocarbon in a weight ratio of 85-10:15-90 in a hydrocarbon solvent and an inert atmosphere in the presence of 0.2 to 20 mmol., per 100 g. of the total amount of the mixture A.sub.1 and the mixture A.sub.2 described below, of a monolithium hydrocarbon calculated as active lithium to form an active copolymer, and after substantial completion of the polymerization, copolymerizing said active copolymer with 92 to 35 parts by weight of a monomer mixture A.sub.2 comprising the same conjugated diolefin having 4 to 6 carbon atoms and monovinyl aromatic hydrocarbon as said mixture A.sub.1 in a weight ratio of 95-20:5-80, such that the total amount of said mixtures A.sub.1 and A.sub.2 is 100 parts by weight, to thereby obtain a final copolymer having a monovinyl aromatic content of 10 to 70% by weight based on the total amount of said mixtures A.sub.1 and A.sub.2. The thus obtained thermoplastic elastomers have at least four polymeric blocks, and are comparable in elastic property to conventional thermoplastic elastomers and excellent in thermal resistance, resistance to oils and processability. Further, said thermoplastic elastomer does not require vulcanization or chemical cross-linking, and can be molded into an article having an excellent shape maintenance property.
