Comparative studies showed that the presence of BaO enhanced the rate of telomerization and increased the total yield of telomers, as well as lowered the average molecular weight of telomers. This effect is decreased in the following order: methanol > ethanol > iso-propyl alcohol.The telomerization was studied over a wide ran...             本工作提出了一种新的引发系统即在MgO或BaO存在下的过氧化叔丁基,应用于四氟乙烯与甲醇、乙醇及异丙醇等低级脂族醇的调节聚合。对比实验证明氧化钡具有提高反应速度和调聚物总收率及降低分子量的作用。此作用对以甲醇为调节剂的反应影响最大,乙醇次之,异丙醇则较小。 研究了四氟乙烯与醇类化合物的克分子比对产物分子量分布的影响。结果表明改变反应物克分子比可以较满意地控制1∶1加成物的生成。以甲醇而言,当反应物克分子比在0.10—0.28范围内,1∶1加成物产率从25.8％增至57％。 从三种醇的调聚产物百分比的比较,得出链转移常数的次序是:甲醇<乙醇<异丙醇。 文摘来源          This paper presents the effect of different initiators and solvents on the anionic polymerization of tert-butyl-vinylketone. An amorphous polymer was obtained with softening point at 140-180° when the title monomer was polymerized with n-butyl lithium as anionic initiator in a homogenous phase with pyridine or tetrahydrofuran as solvent, while that in a heterogenous phase such as benzene, toluene, xylene or n-heptane it would give crystalline and probably isotactic polymer with melting poi...             本文报导了第三丁基乙烯基酮在不同溶剂中应用各种负离子引发剂的聚合研究。以正丁基锂为引发剂,吡啶或四氢呋喃为溶剂时,都是均相聚合,得到无定形聚合物,它们的软化温度为40—180°之间,如果以苯、甲苯、二甲苯或正庚烷为溶剂,则都是非均相聚合,得到结晶性聚合物,有着高达260—280°之间的熔点。上述结晶性与无定形聚第三丁基乙烯基酮的红外光谱有着显著的不同,结晶性聚合物具有特征的吸收峯,以1100厘米~(-1)与1330厘米~(_1)二处最为明显。还研究了不同比例的混合物的红外光谱,当结晶性聚合物含量降至 87％以下时,则 1100厘米~(-1) ,1290厘米~(-1)及 1330厘米~(-1)三处吸收峯逐渐减弱,当减少至13％时则与无定形聚合物的光谱一致。此外金属锂、钠与钾都能引发聚合第三丁基乙烯基酮,也试用了NaH,LiAlH_4,RONa,ROK,RMgX,二苯酮以及二苯酮钠等引发剂进行非均相聚合。 文摘来源          Dodecapeptide ester Ⅰ has been saponified to give a protected C-terminal dodecapeptide (Ⅱ) of the A-Chain of insulin. Further experiments showed that the saponification of ester Ⅰ under various conditions yielded preparations of dodecapeptide Ⅱ varying somewhat in melting points and solubility. These saponification products have been used for the partial synthesis of bovine insulin and all the crude hormone products obtained showed biological activity of 1—4％ of natural insulin in mouse convulsion test.
