Process for producing a block copolymer resin and product thereof |
摘要 |
A continuous process as disclosed which produces a clear, high impact block copolymer having a vinyl aryl monomer content of at least 70 percent of the block copolymer. This continuous process involves the continuous preparation of a multiblock copolymer which comprises the alternate feeding of monomer streams to a reaction zone wherein a product stream is withdrawn from the polymerization system at the same rate as the total rate of the feed streams.
