In this paper, we present data on.. Recently, we found that.... In this paper mechanistic aspects of the polymerization as well as polymerization conditions suppressing decarboxylation are discussed in detail The present work was aimed at studying Here we report the introduction of PEG blocks into the backbone of polycarbonates to form oly(ether carbonate)s. .. The effects of length of the Peg block on the properties of the resulting copolymers were investigated. Correlations were established between the copolymer composition and its material properties such as glass transition temperature, mechanical strength,. and drug release. In addition, preliminary data on the in vitro interaction of cells with these polymers were obtained. In a separate publication, the inverse temperature transitions observed for this class of polymers are described 33 ● Experimental 通常用一般过去时、被动态 根据实验内容通常可见到以下几类: 材料的来源及合成制备 直接买到的药品一般需指明来源 Chemicals<小标题> Amino acid(Bachem), 2-(2-amino-ethyl)pyridine( Fluka) and 2-hydroxypyridine(Acros)were used as received ZnEt, was purchased from Aldrich and was used as received 直接购买的溶剂等辅助药品只需简单提及或略过: All other materials were commercially available and used as received unless otherwise noted All other chemicals were of analytical grade and were used as received 经纯化处理的药品一般需说明纯化方法 Materials<小标题 Cyclotrimethylene carbonate(Ingelheim, Germany) was purified by distillation in vacuo and recrystallized from THF was dried and distilled over CaH2 twice under reduced pressure Ethylacetate was dried over K2 CO3 and distilled7 In this paper, we present data on … Recently, we found that….
