  Polyesters containing side chains and the use thereof

  摘要：

  室温下具有低粘度、相对较高分子量和非常低凝固点的新型羟基聚酯流体，在聚酯链上具有烷基侧链，且这些侧链在聚酯链上呈现出相当规则的排列，最好是未分支或仅略分支的。这些新型聚酯是由单羧酸和/或单烷醇或其酯、醚或聚酯构建组分的反应形成的。经过官能化后，这些新型聚酯可以用于涂料或作为粘合剂，特别优点是它们可以无溶剂或低溶剂含量使用。

  New hydroxyl polyesters fluid at room temperature, with low viscosities at relatively high molecular weight and very low setting points have alkyl side chains in substantially regular arrangement along preferably unbranched or only slightly branched polyester chains, and are formed by the reaction of monocarboxylic acids and/or monoalkanols or their esters of ethers or polyester building components with additional polyester-forming derivatives. The new polyesters can be used to special advantage, after functionalization, for coatings or as adhesives. Especially advantageous is the fact that they can be used without solvents or with a very low solvent content.

  Pressure-sensitive adhesives composed of radiation-cured (meth)acrylic-functional polyesters are prepared from base polyesters, fluid at room temperature, which have molecular weights of 1,000 to 10,000 and branched main chain, and/or from new polyesters having aliphatic side chains bound by ester bridges or, in some cases, ether bridges to the main chain, followed by functionalization of a maximum of 90% of the original hydroxyl groups of the base polyesters by reaction with (meth)acrylate compounds, and crosslinked by electron beam or ultraviolet radiation in a thin coating on a support. The new pressure-sensitive adhesives have the property and the advantage of being cross-linkable by radiation without the use of solvents or diluents.

  Phthalic acid esters have been widely used to improve the plasticity of PVC medical devices. They carry a high exposure risk for both humans and the environment in clinical situations. Our study focuses on the cytotoxicity of alternative plasticizers. Postulated primary metabolites were synthesized, not being commercially available. Cytotoxicity assays were performed on L929 murine cells according to the ISO-EN 10993-5 standard design for the biocompatibility of medical devices. The tested concentrations of plasticizers (0.01, 0.05 and -0.1 mg/m1) covered the range likely to be found in biological fluids coming into direct contact with the medical devices. DEHP, DINP and DINCH were cytotoxic at the highest concentration (0.1 mg/ml) for 7 days of exposure. Their corresponding metabolites were found to be more cytotoxic, for the same concentration. By contrast, TOTM and its corresponding metabolite MOTM were not found to be cytotoxic. DEHA showed no cytotoxicity, but its corresponding monoester (MEHA) produced a cytotoxic effect at 0.05 mg/ml. In clinical situations, medical devices can release plasticizers, which can come into contact with patients. In vivo, the plasticizers are quickly transformed into primary metabolites. It is therefore important to measure the effects of both the plasticizers and their corresponding metabolites. Standard first-line cytotoxicity assays should be performed to ensure biocompatibility.
