摘要:
Conveyor belt, obtainable by application of a block copolymer composition, comprising at least an optionally modified block copolymer, containing at least two terminal poly(vinylaromatic) blocks and at least one internal poly(conjugated diene) block, a non-aromatic plasticizing oil, and a terminal block compatible resin on at least one side of a fabric having from 5 to 25 threads per cm and process for the manufacture of it, while the threads in said fabric have a thickness in the range of from 2.mu. to 300.mu..
摘要:
A process for the manufacturing of elastic articles such as fibers, yarns, or films, from substantially pure selectively hydrogenated block copolymers, comprising at least two blocks predominantly derived from monoalkylene aromatic monomer and at least one block predominantly derived from one or more conjugated dienes and having a number average molecular weight of at least 70,000, comprising the steps of preparing a solution or a gel of said block copolymer with an apolar organic non-aromatic solvent and processing said solution or gel through a fiber forming orifice.
摘要:
a novel process for applying an adhesive to a substrate is disclosed, which process comprises:A. melt blending a monoalkenyl arene/conjugated diene block copolymer, tackifying resin and extending oil to form a hot melt adhesive composition,B. emulsifying the hot melt with water and an emulsifying agent, andC. applying the resulting emulsion as a film on a substrate.Preferably, the block copolymer is a styrene/isoprene block copolymer and the tackifying resin is selected from the group consisting of diene-olefin copolymers, hydrogenated resins, esters of resin, polyterpenes, terpenephenol resins, and polymerized mixed olefins.
