摘要:
This invention relates to a process for first preparing a free flowing finely divided powder of a neutralized sulfonated elastomer and subsequently and optionally admixing said formed powder with other agents such as fillers and oils thereby providing free flowing powders capable of being subsequently fabricated into tough elastomeric objects. The neutralized sulfonated elastomeric polymer can be converted into a free flowing finely divided powder which does not agglomerate or cold flow under ambient conditions by a variety of processes, preferably by a grinding process conducted at low temperatures. The formed powder of the neutralized sulfonated elastomeric polymer is blended with at least one chemical additive into a homogeneous mixture, wherein the chemical additive is selected from the group including fillers, polyolefinic thermoplastics, non-polar backbone process oils, lubricants or a metallic oxide and mixtures thereof. The homogeneous mixture is formed into a finished elastomeric article by conventional fabrication.
