摘要:
A disk substrate prepared from a blend of poly(arylene ether) resin and poly(alkenyl aromatic) resin is disclosed. The substrate can be used in data storage media having dimensional stability and good molded-in features.
摘要:
A method of making an optical film comprises heating the optical film comprising greater than or equal to 80 wt. % polycarbonate to a sufficient temperature to stretch the optical film, wherein the weight percent is based on a total weight of the optical film; and stretching the optical film, wherein a resulting stretched optical film has a linear CTE measured in a direction parallel to a stretching direction of less than or equal to 50×10−6 cm/cm/° C.
