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: An interpenetrating polymer network (IPN) or semi-interpenetrating polymer network (semi-IPN) comprises a first phase which is continuous and comprises a flexible polymer and a second phase which is a fluorescent or nonfluorescent durable dispersed or continuous phase and comprises a dye and a polymer, wherein the polymer enhances durability of the dye. Such networks are particularly useful in fluorescent traffic signs or safety devices or in pavement marking tape or paint.
