摘要： A system and process for purifying a 1,3-butadiene feedstock containing 1,3-butadiene and various impurities by first introducing the 1,3-butadiene feedstock stream to a separation column to produce an intermediate product stream containing 1,3-butadiene and residual impurities and then introducing the produced intermediate product stream through a condenser to a suitable dryer for removing residual impurities from the intermediate product stream and thereby forming a purified 1,3-butadiene stream. The separation column separates an overhead stream, containing 1,3-butadiene and impurities such as propadiene, water and oxygen, and a bottoms stream, containing impurities such as polymerization inhibitor, ethyl acetylene, 1,3-butadiene dimer, pentane and 1,2-butadiene, from the intermediate product stream which leaves the separation column in the form of a vapor side draw stream.

摘要： A monovinyl arene, such as styrene, is polymerized with a monofunctional lithium initiator, followed by addition of a conjugated diene, such as butadiene, with additional monofunctional lithium initiator. The resultant block copolymers are coupled to give linear coupled block copolymers or radial coupled block copolymers with a random distribution of homopolymer and copolymer branches. The polymers exhibit increased tack and improved creep resistance in adhesive compositions. The amount of initiator added as the second increment with the second monomer must be greater than the amount added as the first increment with the first monomer.
