摘要： The present invention comprises a stabilized halogen containing polymer, preferably poly(vinyl halide), and more preferably poly(vinyl chloride) composition. A preferred polymer composition is a rigid halogenated polymer such as rigid poly(vinyl chloride). The composition contains at least one metal salt selected from the group consisting of at least one carboxylic acid or derivative thereof having at least two carboxyl groups, at least one carboxyl group and at least one hydroxyl group, at least one carboxyl group and at least one mercaptan, and an aromatic carboxylic acid having at least one carboxyl group. The metal salt is most preferably disodium adipate.

摘要： A telescoping work platform having telescoping inner and outer frames that are telescopically adjustable and are capable of being locked relative to one another. The inner frame has a bottom wall at its lower end which serves as a work platform and is provided at its upper end with safety rails for stabilization of the user. The outer frame is provided with pivotal ladder rungs to permit climbing by the user and to permit user access to the work platform at all selected positions of the inner and outer frames. The work platform is also provided with retractable transport wheels and wheel actuators to permit stable use of the work platform and to permit wheeled transport of the work platform when its movement is desired.
