Abstract: The present invention provides: a copolymer (A) which is a copolymer obtained by copolymerizing one or plural cycloolefin monomers and one or plural acyclic olefin monomers, or by copolymerizing two or more cycloolefin monomers, wherein a glass transition temperature (Tg) is 100° C. or higher, a refractive index is 1.545 or higher, and an Abbe's number is 50 or larger; a polymer (B) selected from: a ring-opening homopolymer obtained by ring-opening polymerization of only a monomer represented by formula (I), a ring-opening copolymer obtained by ring-opening copolymerization of the monomer represented by formula (I) and a monomer capable of ring-opening copolymerization with the monomer represented by formula (I), a hydrogenated product of the ring-opening homopolymer and a hydrogenated product of the ring-opening copolymer; a forming material containing the copolymer (A) or the polymer (B); and a resin formed article obtained by forming the forming material.

Abstract: The purpose of the present invention is to provide an assembly method for manufacturing with which deformation caused by heating during joining is inhibited, peeling apart of the assembly is facilitated, protein adsorption is suppressed, and low haze is achieved. An assembly [3] includes one or more types of shaped products [1] that are joined via a joining layer [2] having a material constitution different from the shaped products; and a method for manufacturing the same. The joining layer [2] contains: 100 parts by weight of a cycloolefin resin [4]; and a softening agent [5]. The content of the softening agent [5] in the joining layer [2] is 6 parts by weight to 99 parts by weight of the softening agent [5] relative to 100 parts by weight of the cycloolefin resin [4]. The joining layer [2] has a haze of 1.0 or less.
