Abstract
Provided for preparing thermoplastic polymer blends is (1) an apparatus comprising a grinder, a mixer, at least one material transfer device, a weigh scale, means for addition of additives to the mixer, a storage vessel, a processing device and means for feeding polymer to the processing device; and (2) a process comprising mixing a known amount of a first material with a desired amount of at least one additive based on a predetermined weight ratio of additive to first material to form individual batches of pre-mix, storing the pre-mix batches in a storage vessel, continuously feeding the pre-mix from the storage vessel to a processing device, adding a polymer stream to the processing device at a rate based on the first material feed rate to the processing device, optionally adding at least one vulcanizing agent stream to the processing device at a rate based on the polymer stream feed rate to the processing device and melt mixing all materials in the processing device to form a thermoplastic polymer blend.
