Document Type and Number:
Japanese Patent JP5156343
Kind Code:
B2
Abstract:
Use of a synthetic wax oxidate (I) having a number-average molecular weight of 300-1000 g/mol measured via high-temperature GPC according to ASTM D 6474-99 and an acid number of 15-60 mg potassium hydroxide (KOH)/g as determined according to DIN 53 402, as a processing aid for molding mass comprising a polar polymer having repeating units, is claimed, where at least 60% of the repeating units contain at least one of ester-, amide-, sulfone- and imide groups. Independent claims are included for: (1) the molding mass comprising the polar polymer and (I) (0.05-1.5 wt.%); and (2) a molding part for optical applications, produced from the molding mass.
