    • Synthetic absorbable sutures are prepared from copolyoxalate polymers having isomorphic sequences. The polymers are derived from mixtures of cyclic and linear diols, each having the same carbon chain length of 6 or 8 atoms. The cyclic diol may be aliphatic or aromatic. The diols are polymerized with dialkyl oxalate, preferably in the presence of an inorganic or organometallic catalyst, to obtain a highly crystalline isomorphic copolyoxalate polymer which is melt extruded and drawn to form oriented filaments. The filaments are characterized by good initial tensile and knot strength and a high order of softness and flexibility. When implanted in living animal tissue, the fibers have good strength retention over a period of at least 21 days and eventually absorb with a minimal degree of adverse tissue reaction.
    • 合成可吸收缝线由具有同构序列的共聚草酸酯聚合物制备。 聚合物衍生自环状和线性二醇的混合物,每一种具有相同的碳链长度为6或8个原子。 环状二醇可以是脂肪族或芳香族的。 二醇与草酸二烷基酯进行聚合,优选在无机或有机金属催化剂的存在下进行聚合,得到熔融挤出和拉伸形成定向长丝的高度结晶的同晶共聚草酸酯聚合物。 长丝的特征在于初始拉伸强度和结强度高,柔软度高的柔顺性。 当植入活的动物组织中时,纤维在至少21天的时间内具有良好的强度保留,并且最终以最小程度的不良组织反应吸收。
