Abstract: Permanent antistatic properties are imparted to melt-formed polymers by the incorporation therewith of a polymer composition prepared by reacting a hydrogen-reactive compound with an alkylene oxide adduct of a nitrogen-containing compound. Further, the polymer composition may be capped to minimize reaction with the melt-formed polymer.

Abstract: Polyesters containing ionic groups are prepared by the reaction of an alkylene oxide adduct of a nitrogen-containing compound with (1) a metal salt of an acidic derivative of an organic polycarboxylic ester or (2) an alkoxide-generating reagent followed by reaction with a polycarboxylic anhydride, anhydride acid chloride, or anhydride ester. The polyesters are particularly useful in the preparation of antistatic polymer compositions.

Abstract: A system for automatically loading and tensioning a supply reel of magnetic recording which is contained in a tape cassette. The system is designed to be utilized with a tape transport mechanism of the type wherein the supply reel is driven by surface engagement of the outermost layer of tape on the reel with a capstan. A motor driven leadscrew mechanically engages the tape transport apparatus and functions as a means for sequencing its operation in a manner so that upon loading, the normally-closed cassette is opened and the tape pack is advanced by the transport apparatus into an operative position in which it is in contact with the capstan. Following the threading of the tape about the take-up reel, the leadscrew causes the transport apparatus to withdraw the supply tape pack from close contact with the capstan in order to allow slack to be removed therefrom through the action of a brake upon the supply reel.

Abstract: Baking finishes which do not pollute the environment and which comprise a mixture of a polymer having hydroxyl groups, a furoxane of the formula ##STR1## WHERE R is a 2n-valent hydrocarbon radical of 2 to 20 carbon atoms and n is an integer from 1 to 4, and, if appropriate, suitable assistants.
