摘要： The production of a protein free synthetic polyisoprene which has both low levels of chemical impurities and good physical properties has yet to be realized. It has now been envisioned that the use of neodymium catalyzed polyisoprene will offer the combined advantages of both a clean, as well as, high cis-1,4 polymer. Synthesis of polyisoprene rubber using a neodymium based catalyst system is described. Characterization of the material shows the absence of an ultra high molecular weight fraction and the presence of very high cis-1,4-microstructure. Gum stock and black filled compound studies comparing neodymium polyisoprene with natural rubber, titanium polyisoprene, and lithium polyisoprene have been performed. Results indicate that polyisoprene rubber synthesized using a neodymium catalyst system (Nd—PI) has similar stress-strain and tear properties as synthetic titanium polyisoprene. Analysis of residual volatile, extractable, and oligomer levels indicates Nd—PI is indeed a clean source of high cis synthetic polyisoprene. In the practice of this invention such Nd—PI is used in manufacturing articles used in manufacturing health care products, garments, clothing, and food and beverage packaging. Some specific applications include: bandages, drug delivery patches, suture tape, pharmaceutical closures, including syringe plungers and sleeves, vial closures and stoppers, tourniquets, exercise bands, condoms and prophylactic devices, gloves and glove dip, intervenous bags and tubing, baby bottle nipples, pacifiers, and teething devices, breast hoods, and dental and orthodontic devices.
摘要翻译：具有低水平的化学杂质和良好物理性质的无蛋白质合成聚异戊二烯的生产尚未实现。现在已经设想到，使用钕催化的聚异戊二烯将提供清洁的以及高顺式-1,4聚合物的组合优点。描述了使用钕基催化剂体系合成聚异戊二烯橡胶。该材料的表征显示不存在超高分子量级分和非常高的顺式-1,4-微结构的存在。已经进行了比较钕聚异戊二烯与天然橡胶，钛聚异戊二烯和锂聚异戊二烯的胶料和黑色填充的化合物研究。结果表明，使用钕催化剂体系（Nd-PI）合成的聚异戊二烯橡胶与合成钛聚异戊二烯具有相似的应力 - 应变和撕裂性能。残余挥发性，可萃取和低聚物含量的分析表明，Nd-PI确实是高顺式合成聚异戊二烯的清洁来源。在本发明的实践中，这种Nd-PI用于制造用于制造保健产品，衣服，衣服和食品和饮料包装的制品。一些具体应用包括：绷带，药物输送贴片，缝合胶带，药物封闭物，包括注射器柱塞和袖子，瓶盖和塞子，止血带，运动带，避孕套和预防装置，手套和手套浸液，干涉袋和管，婴儿奶瓶乳头，奶嘴和出牙装置，胸罩，牙科和正畸装置。
