To provide an ETFE film which is unlikely to wrinkle when stretched and retracted, and a method for producing the same. It is an ethylene-tetrafluoroethylene copolymer film characterized in that the crystallinity obtained by the formula (1) from the peak area S.sub.20 in the vicinity of 2=20, the peak area S.sub.19 in the vicinity of 2=19 and the peak area S.sub.17 in the vicinity of 2=17 in the diffraction intensity curve obtained by the X-ray diffraction method, is from 55 to 70%, and the proportion of the quasi-crystal layer obtained by the formula (2) is from 10 to 20%:
crystallinity (%)=(S.sub.19+S.sub.2)/(S.sub.17+S.sub.19+S.sub.20)100(1)
proportion of quasi-crystal layer (%)=S.sub.20/(S.sub.17+S.sub.19++S.sub.20)100(2).

A polyphenylene sulfide resin composition is obtained by mixing a polyphenylene sulfide resin (a), a fluororesin (b) and an organosilane compound (c). When a resin phase-separated structure of a molded product formed from the polyphenylene sulfide resin composition is observed by an electron microscope, the component (a) forms a continuous phase, the component (b) forms a primary dispersed phase having a number-average dispersion diameter of not greater than 1 m, and a secondary dispersed phase of the component (a) is included in the primary dispersed phase of the component (b).

Adhesive tapes include a plasticized polyvinyl chloride backing, a primer including an ethylene/carbon monoxide-containing terpolymer and a styrene-containing block copolymer, and an adhesive.

Silane-crosslinkable polymeric compositions comprising a polyolefin having hydrolyzable silane groups, an acidic silanol condensation catalyst, and a phenolic antioxidant. The phenolic antioxidant comprises two sulfur-containing radicals, one located at the ortho position and the other located at the para position relative to the hydroxyl group of the phenol. Such crosslink able polymeric compositions can be employed in various articles of manufacture, such as in the wire and cable industry.
