标准范围
ISO 7270-1:2005规定了通过热解和随后的气相色谱法测定原橡胶或硫化或未硫化化合物中共聚物或均聚物和/或共聚物混合物中苯乙烯(STY)/丁二烯(BD)/异戊二烯(IP)比率的原理和程序。它适用于由苯乙烯、丁二烯和异戊二烯组成的共聚物/三元共聚物,以及这些聚合物的混合物。
ISO 7270-1:2005 specifies the principles and procedures for determining, by pyrolysis and subsequent gas chromatography, the styrene (STY)/butadiene (BD)/isoprene (IP) ratio in copolymers, or blends of homopolymers and/or copolymers, in raw rubbers or vulcanized or unvulcanized compounds.It is applicable to copolymers/terpolymers consisting of styrene, butadiene and isoprene, and blends of these polymers.
