    摘要： The invention is drawn to radial block copolymers of the formula:(pS--pI--pB).sub.n Xwherein pS is polystyrene, pI is polyisoprene, pB is polybutadiene, X is the residue of a multifunctional coupling agent used in the production of the radial block copolymer, and n is a number greater than or equal to 3 representative of the number of branches appended to X; pressure sensitive adhesive compositions comprising such radial block copolymers and articles of manufacture produced therefrom. The pS component of the radial block copolymers of this invention comprise from about 14 to about 24 parts per 100 parts by weight of the radial block copolymer; the molecular weight (as polystyrene equivalent) of the radial block copolymer is between about 200,000 to about 400,000; and the weight amount of polybutadiene in the pI--pB segment is less than 50 weight percent.

    摘要： Radial block copolymers characterized by the formulas: (1) (pS-pI).sub.n X and (2) (pS-pI-pB).sub.n X where pS is polystyrene, pI is polyisoprene, pB is butadiene, X is a residue of a multifunctional coupling agent used in the production of the radial block copolymer, and n is a number greater than 2 representative of the number of branches appended to X; hot-melt adhesive compositions constituted of said radial block copolymers, and articles of manufacture produced therefrom. These copolymers possess blocks of high average molecular weight polystyrene (10,000 to 25,000) and an overall average molecular weight (90,000 to 380,000) such that when blended in requisite proportions with a compatible tackifier resin, preferably also a secondary tackifying resin or plasticizing oil, and stabilizer, superior hot-melt adhesive compositions can be formed. The hot-melt adhesive compositions possess, inter alia, superior heat resistance, superior static time to failure with low viscosity, good peel adhesion, good tack, and high ability to bond to a polyethylene or polypropylene substrate at temperatures below that which may damage the substrate.
