Abstract: A hot melt adhesive, a laminar structure, and non-woven article fabricated from a blend comprising:from about 50 percent by weight to about 5 percent by weight of a butene-1 homopolymer or copolymer;from about 50 percent by weight to about 95 percent by weight of a tackifying resin;from a 0.01 to about 1 phr of a nucleating agent;up to about 1 part per hundred (phr) of a stabilizer;up to about 30 phr of a plasticizer; andup to about 30 phr of a wax.

Abstract: A laminar structure comprising a substrate and a hot melt adhesive, wherein said hot melt adhesive comprises:(A) a butene-1 polymer blend of from 10% by weight of 90% by weight of an at least partially crystalline copolymer of butene-1 and ethylene, wherein the ethylene content is from about 1 mole % to about 20 mole % of said copolymer, and from 10% by weight to 90% by weight of a butene-1 homopolymer;(B) from about 20% by weight to about 60% by weight of a substantially non-polar tackifying resin selected from the group consisting of polyterpene and aliphatic resins from C.sub.5 -C.sub.9 hydrocarbon streams or hydrogenated resins thereof with softening points in the range of 70.degree. C. to 130.degree. C.; and(C) from about 0.1 phr to about 0.5 phr of an antioxidizing agent.

Abstract: Improved impact vinyl aromatic compositions are disclosed comprising interpolymers containing (A) from about two to about 25 parts by weight of a mixture of (1) a polybutadiene rubber with (2) a polyisoprene rubber in a weight ratio between 35:65 and 65:35; and (B) from about 98 to about 75 parts of at least one poly(monovinylaromatic) compound.

Abstract: It is herein disclosed, a process for polymerizing butene-1 into homopolymers and copolymers, using a catalyst system containing titanium trichloride, diethylaluminum chloride, and a substituted phenol in specified molar proportions. It is further disclosed, products made by the inventive process, and articles of manufacture made from these products.

Abstract: It is herein provided a polymer composition having and exhibiting improved bonding to incompatible materials comprising functionalized high melt flow polyolefins and unfunctionalized polyolefins. More specifically, these compositions have and exhibit improved adhesion to polar materials, and improved dyeability and printability.
