究其原因，与传统的超塑化剂萘磺酸和磺化三聚氰胺缩合物相比，他们能在低掺量下赋予混凝土高分散性及高分散体系稳定性防止塌落度

The results showed that intermidiate 1, 2-propanediol-sebacate of low relative molecular mass was synthesized with toluene-p-sulfoinc acid as catalyst, benzene as watercarrying agent, and of mole ratio of sebacic acid to 1, 2-propanediol of 1:4. The glass-transition temperatures of PPSC were below 0 ℃ which confirmed that PPSC would be in a high-elastic state of ambient temperature and human body temperature. PPSC was a elastomer with moderate crosslinkage, low module and high elongation, and had rapid degradation ratio (degradation degree more than 50%) in phosphate (pH value 7.4) at 37℃.

结果表明，以对甲苯磺酸为催化剂、苯为带水剂，在酸醇比为1，4的条件下可合成较低相对分子质量的中间体癸二酸聚酯二元醇；PPSC弹性体的玻璃化转变温度在0℃以下，于室温及人体温度下处于高弹态；PPSC为适度交联的、低模量高伸长的弹性体，其在37℃、pH值为7.4的磷酸盆缓冲溶液中具有较快的降解性（降解度超过50%）。

Accordingly a further feature of the invention is a combined process wherein a dialkyl phenylethylmalonate is made from an alkyl phenylacetate and a dialkyl carbonate by a process comprising adding to a quantity of sodium which is covered with a hydrocarbon solvent boiling above 100°C, at least a chemically equivalent proportion of a lower aliphatic alcohol, subsequently adding an approximately equivalent proportion of a dialkyl carbonate and of an alkyl phenylacetate, heating the mixture to induce reaction and continuously distilling out the alcohol formed from the reaction zone and finally causing the sodio diethyl phenylmalonate so obtained to interact with an ethylating agent, such as ethyl halide, diethyl sulphate of ethyl p-toluene-sulphonate.

因此，本发明的另一个应用是一个组合工艺过程：二烷基苯基乙基丙二酸酯由烷基乙酸苯酯和二烷基碳酸酯得到，具体工艺过程是：向覆盖有沸点超过一百摄氏度的团庆化合物溶剂的金属钠中添加至少化学平衡的低级脂肪族醇，然后加入大约相同当量的二烷基碳酸酯和烷基乙酸苯酯，加热混合物引导反应进行，持续蒸馏把形成的醇类从反应区域移出，最后使获得的二乙基苯基丙二酸酯和乙基化试剂如卤代乙烷，二乙基硫酸酯形成乙基p-甲苯磺酸酯。
