Disclosed is a molding a molding for mounting a window glass on the window opening of an automotive body, said molding for automobile windows comprising a flexible leg portion, an upper flange portion which extends toward both sides at an upper part of the leg portion and supports the edge portion of the glass, upper lip portions that form both tips of said upper flange portion, and lower lip portion which are adhered to the window opening of the automotive body, wherein at least the upper lip portions and the lower lip portions of said molding are formed by using a thermoplastic olefinic elastomer or a composition of said elastomer and an olefin-ethylene type unsaturated carboxylic acid copolymer or a salt thereof having a hardness in compliance with JIS A of from 50 to 80, said leg portion and said flange portion are formed by using a blend of the thermoplastic olefinic elastomer and the olefin-ethylene type unsaturated carboxylic acid copolymer or a salt thereof, said blend having a hardness in compliance with JIS A of from 75 to 95, the surfaces of the upper lip portions are covered with a layer which contains the olefin-ethylene type unsaturated carboxylic acid copolymer or a salt thereof and having a thickness of 1 to 50 .mu.m and a hardness in compliance with JIS A of greater than 85, and at least the lower surfaces of the lower lip portions are formed by using the olefin-ethylene type unsaturated carboxylic acid copolymer or a salt thereof or a polymer composition containing them.

Disclosed is an ionomer composition comprising (A) an ionomer formed by neutralizing a carboxyl group of an ethylene/unsaturated carboxylic acid copolymer with an transition metal cation, (B) a polyamide and (C) a polyamide oligomer having a terminal group of the molecule chain blocked with a primary amino group. Since two polyamide components differing in the degree of polymerization are incorporated in this ionomer composition, excellent characteristics of the ionomer resin are related in the ionomer composition, and the mechanical strength at high temperatures, the formability and the transparency are prominently improved.
