摘要： The invention provides a hot melt adhesive composition including a tubular reactor copolymer of ethylene and 5 to 20 mol% of comonomer units derived from an alkyl acrylate or alkyl methacrylate, wherein the copolymer has a melt index of at least 300g/10 min. The alkyl group of the alkyl acrylate or alkyl methacrylate can be a linear or branched C 1 to C 12 group, particularly n-butyl. If desired, the hot melt adhesive can further include tackifiers, waxes, antioxidants and other desired additives. The hot melt adhesive composition shows improved heat resistance and favorable properties, such as has a shear adhesion fail temperature of at least 80°C, without the need to use high melting waxes. The invention further provides articles such as cartons, cases, trays bookbindings or disposables including the hot melt adhesive compositions.
摘要翻译：本发明提供一种热熔粘合剂组合物，其包括乙烯的管式反应器共聚物和5至20摩尔％的衍生自丙烯酸烷基酯或甲基丙烯酸烷基酯的共聚单体单元，其中该共聚物的熔体指数为至少300g / 10分钟。丙烯酸烷基酯或甲基丙烯酸烷基酯的烷基可以是直链或支链C1至C12基团，特别是正丁基。如果需要，热熔粘合剂还可以包括增粘剂，蜡，抗氧化剂和其它所需的添加剂。热熔粘合剂组合物显示出改善的耐热性和良好的性能，如剪切粘附失效温度至少为80℃，而不需要使用高熔点蜡。本发明还提供了诸如纸箱，箱子，托盘书签或包括热熔粘合剂组合物的一次性物品的物品。

摘要： The invention is drawn to radial block copolymers of the formula: (pS-pI-pB)nX wherein 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)nX and (2) (pS-pI-pB)nX 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.
