摘要： A dental floss comprising a porous PTFE fiber having a density of less than about 0.7 g/cc. The inventive floss is abrasion resistant, grippable and has a soft feel to the hands and a rough feel in the mouth. The floss is made by an extrusion process with non-contact heating during subsequent expansion with amorphous locking.

摘要： A polymerization process for producing a copolymer of tetrafluoroethylene and (perfluorobutyl)ethylene, prepared by an aqueous dispersion polymerization technique, and the resin produced thereby, are provided. This copolymer contains a relatively small amount, between about 0.02 weight percent and about 0.6 weight percent, of comonomer polymerization units. The copolymer is believed to be comprised of a core-shell structure wherein the polymerized comonomer units reside primarily within the core. The primary particle size of the copolymer ranges from 0.175 microns to and including 0.203 microns and the standard specific gravity is less than 2.143. This copolymer possesses a unique combination of very small particle size coupled with high molecular weight, a combination not heretofore achieved in tetra-fluoroethylene polymers of the dispersion or fine powder type. The process of this invention is characterized by permanganate initiation and the entire reaction is carried out in the absence of zinc chloride or other ionic strength enhancer. The addition of initiator must be stopped well before completion of the reaction, preferably at or before the mid-point of the complete reaction.
摘要翻译：提供了通过水分散聚合技术制备的四氟乙烯和（全氟丁基）乙烯的共聚物的聚合方法和由其制备的树脂。该共聚物含有相对少量的约0.02重量％至约0.6重量％的共聚单体聚合单元。该共聚物被认为是由核 - 壳结构组成，其中聚合的共聚单体单元主要存在于芯中。共聚物的一次粒径为0.175微米至0.203微米，标准比重小于2.143。该共聚物具有与分子量或细粉末类型的四氟乙烯聚合物中迄今未得到的结合的高分子量非常小的粒度的独特组合。本发明的方法的特征在于高锰酸盐引发，整个反应在不存在氯化锌或其它离子强度增强剂的情况下进行。引发剂的加入必须在反应完成之前停止，优选在完全反应的中点或之前。
