Abstract: A sampler assembly and a method of collecting a sample of a process are disclosed. The sampler assembly includes a lid subassembly and a housing body subassembly. The housing body subassembly includes a housing body that accommodates different sizes and shapes of collection bottles. The housing body includes lateral and axial adjustment devices with bottle engaging pads with surfaces that contact and support the collection bottle. The adjustment devices may be either manually or automatically adjusting components, and may be adjusted for any type of collection bottle. The lid subassembly includes a lid, a bracket coupled to the lid for supporting the sampler assembly, a plug disposed in the lid, a supply line and a vent line. The housing body subassembly includes a housing body releasable coupled to the lid, lateral and axial adjustment devices, and a shield to protect the operator.

Abstract: A process for the preparation of a maleated polyethylene wax is disclosed. This process entails mixing in the melt phase polyethylene, maleic anhydride, free radical initiator and a chain transfer agent m-di-isopropylbenzene. This process can be a continuous process either in a stirred reactor or twin screw extruder. The resulting maleated polyethylene wax has a high acid number, essentially no objectionable odor, and a Gardner color number less than 3.
