Aluminum-polyethylene laminates

Aluminum-polyethylene laminates. Yamada, Mitsuo; Hazama, Keiji; Ohta, Shinichi (Hitachi Chemical Co., Ltd., Japan). Japan. Kokai JP 52078983 2 Jul 1977 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B32B015-08. APPLICATION: JP 75-157509 25 Dec 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Silane-modified polyethylene (I) [9002-88-4] films and metal sheets are pressed to give laminates having good peel strength. Thus, a mixt. of high-d. I 100, trimethoxyvinylsilane (II) [2768-02-7] 1.5, and dicumyl peroxide 0.05 part was extruded at 250.degree. to give a 60-.mu. film having tensile strength 250 kg/cm2, dielec. const. 2.3, dielec. loss <2 .times. 10-4. The film was placed between 2 Al sheets preheated at 300.degree. and pressed to form a laminate having peel strength 1000 g/in., compared with 300 g/in. for a similar laminate of unmodified I.

Crosslinking of silane-modified polyethylene films

Crosslinking of silane-modified polyethylene films. Hashimoto, Hiroshi; Kato, Masahiro; Nishizawa, Hitoshi (Showa Electric Wire and Cable Co., Ltd., Japan). Japan. Kokai JP 52069951 10 Jun 1977 Showa, 2 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L023-02. APPLICATION: JP 75-146560 9 Dec 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Vinylsilane-grafted polyethylene (I) [9002-88-4] films are treated with dibutyltin dilaurate (II) [77-58-7] vapor to give crosslinked films. Thus, a mixt. of low-d. I 100, trimethoxyvinylsilane [2768-02-7] 2, dicumyl peroxide 0.25, and antioxidant 0.5 part was heated 5 min at 200-30.degree., rolled at 130-40.degree., and pressed at 130-40.degree. to give a 1-mm sheet. The sheet was immersed 1 min in H2O and heated 2 h in II vapor at 100.degree. to crosslink the film to 60%.
