    • The present invention relates to 4-methyl-1-pentene polymer compositions. Specifically, the present invention relates to adhesive compositions comprising the 4-methyl-1-pentene polymers used in bonding a 4-methyl-1-pentene polymer layer and a polar-group-containing resin layer, and laminates obtained by using such compositions. The 4-methyl-1-pentene polymer compositions as these adhesive compositions comprise a 4-methyl-1-pentene polymer (A); and a modified polyolefin resin (B) comprising a mixture of an unsaturated carboxylic acid-modified a-olefin polymer (B-1) whose &agr;-olefin is selected from a group of propylene, butene-1 and 4-methyl-1-pentene and an unsaturated carboxylic acid-modified ethylene-&agr;-olefin copolymer (B-2). In these compositions, an unsaturated carboxylic acid-modified 4-methyl-1-pentene polymer (A′) showing a particular modification rate and a particular melt flow rate may be used in place of (A) and (B-1). These compositions have excellent adhesion to polar-group-containing resins having the OH group and the NH group, among others. The laminates obtained by laminating a 4-methyl-1-pentene polymer layer and a polar-group-containing resin layer via any of these compositions show excellent interlaminar adhesion (average peel strength) and yet heat resistance.
    • 本发明涉及4-甲基-1-戊烯聚合物组合物。 具体地,本发明涉及包含用于结合4-甲基-1-戊烯聚合物层和含极性基团的树脂层的4-甲基-1-戊烯聚合物的粘合剂组合物和使用这些组合物获得的层压体。 作为这些粘合剂组合物的4-甲基-1-戊烯聚合物组合物包含4-甲基-1-戊烯聚合物(A); 和包含α-烯烃选自丙烯,丁烯-1和4-甲基-1-戊烯的不饱和羧酸改性的α-烯烃聚合物(B-1)的混合物的改性聚烯烃树脂(B) 和不饱和羧酸改性的乙烯-α-烯烃共聚物(B-2)。 在这些组合物中,可以使用显示特定改性速率和特定熔体流动速率的不饱和羧酸改性的4-甲基-1-戊烯聚合物(A')来代替(A)和(B-1)。 这些组合物对具有OH基和NH基的含极性基团的树脂等具有优异的粘附性。 通过这些组合中的任何一种层压4-甲基-1-戊烯聚合物层和含极性基团的树脂层获得的层压体显示出优异的层间粘合(平均剥离强度)和耐热性。
