    摘要： There is provided pressure-sensitive adhesive coated breathable nonwoven tape backing substrate where the nonwoven tape backing comprises a fibrous nonwoven web formed in part by multicomponent fibers having an adhesive component region. The multicomponent fibers are distributed throughout the width dimension of the nonwoven tape backing such that adhesive component region is exposed on both outer faces of the nonwoven tape backing. The adhesive component region is preferably a pressure-sensitive adhesive region formed by hot melt coextrusion of at least two components to form the multicomponent fibers. A pressure-sensitive adhesive tape layer is coated onto at least one face of the nonwoven tape backing which pressure-sensitive adhesive tape layer is preferably of the same type of adhesive as that forming the adhesive region of the multicomponent fiber or is at least compatible with the adhesive region of the multicomponent fiber such that the adhesive has enhanced adhesive properties to the pressure-sensitive adhesive tape layer.

    摘要： The present invention relates to pressure-sensitive adhesive compositions comprising tackified elastomeric copolymers or block copolymers, e.g., based upon styrene/isoprene, having a novel condensed phase structure wherein polymer branches occur along the polymer backbone, either at a predetermined location or at random locations. The invention also provides sheet materials coated with the adhesive compositions. The polymers of the present invention are made by a method which comprises the step of reacting under polymerization conditions, hydrocarbyl lithium initiator, at least one anionically polymerizable compound, and an organometallic-substituted styrene condensing agent. The reactants may be added simultaneously to produce a copolymer with polymer branch segments randomly located along the polymer backbone or sequentially to produce a copolymer with branches located at the same predetermined location along the polymer backbone. The resultant polymers may be further reacted with a linking agent to form multi-arm copolymers. The resultant elastomeric polymers are compatible with any of a wide variety of known tackifier resins and plasticizers to produce unique pressure-sensitive adhesive compositions.
