摘要： A novel release liner is provided which has a release surface comprising a syndiotactic polymer. The release liners of the present invention offer superior release to a wide variety of materials without the application of release agents, have relatively high heat distortion temperatures, and are unaffected by radiation sources used to cure most polymeric compositions. The release liners of the present invention can be microreplicated with a pattern which can be transferred to coatings and other impressionable materials to impart unique physical or optical properties. Thus, a method of producing a patterned article is also provided, as is a method of producing a solid object from a curable composition.

摘要： A novel microprismatic retroreflective film or sheeting is provided which comprises a transparent semicrystalline polymer. The microprismatic retroreflective film or sheeting of the present invention offers superior retroreflective brightness at large angles of incidence and at large observational angles. Syndiotactic vinyl aromatic polymers, especially syndiotactic polystyrene and copolymers thereof, are preferred semicrystalline polymers, as they impart good dimensional stability and resistance to moisture, and can be made resistant to UV radiation. Signing materials comprising these microprismatic retroreflective films provide improved performance for off-angle illumination and viewing in traffic control and other signing applications.

摘要： A UV weatherable film construction is provided which is capable of retaining its dimensional stability under extreme environmental temperatures and humidities. The base film polymer, syndiotactic polystyrene, has characteristically low moisture absorption, excellent thermal stability, and high transparency. When used in combination with a UV-blocking coating, the sPS film exhibits a degree of resistance to UV-induced discoloration and degradation that is substantially superior to unprotected sPS films or films based on sPS resins that are merely compounded with a UV absorber. The sPS cover films of the present invention are useful as overlay films in signing and other outdoor applications, are comparable to UV-absorber loaded acrylic films in UV blocking or resistance, and provide a cost competitive alternative to acrylic, polyester, and fluoropolymer overlay films.
摘要翻译：提供一种UV耐候性薄膜结构，能够在极端的环境温度和湿度下保持其尺寸稳定性。基膜聚合物，间同立构聚苯乙烯具有低吸湿性，优异的热稳定性和高透明度的特征。当与UV阻挡涂层组合使用时，sPS膜表现出对UV诱导的变色和降解的抗性程度，其基本上优于基于仅与UV吸收剂复合的sPS树脂的未保护的sPS膜或膜。本发明的sPS覆盖膜可用作签字和其它室外应用中的覆盖膜，可与紫外线吸收剂加载的丙烯酸膜相比具有UV阻挡或抗电阻性，并且提供了具有成本竞争力的替代丙烯酸，聚酯和含氟聚合物覆盖膜。

摘要： Retroreflective articles having multilayer films are useful for commercial graphics and retroreflective products, such as roll-up signs for highway transportation safety. The articles comprise multilayer films having at least one layer of polyurethane and at least one layer of a copolymer of alkylene and at least one non-acidic, polar co-monomer. Articles having the new multilayer films provide the same or improved performance, are less expensive, and offer improved methods for manufacturing, when compared to prior articles.
