Ensure competent execution and documentation of inspection and test activities as specified in approved itps. 保证能执行批准的检验与试验计划(itp)中规定的检验与试验活动并编制相关文件;
The influence of t butyl and n butyl lithium initiator, butadiene and styrene ratio, coupler, butylenes oxide, mixed protective agent and fine treat on synthesis of star type block butadiene styrene copolymerization resin with transparent and impact ( abbreviation as ITPS) were discussed. 研究了以丁基锂为引发剂,在环己烷溶剂中合成抗冲及透明性颇佳的星型丁二烯-苯乙烯共聚嵌段树脂(简称为ITPS)主要的影响因素。
The result shows that the transparent of ITPS was fairly good by n butyl lithium initiator; 结果表明以正丁基锂为引发剂制备的ITPS透明性好;
