<p>PURPOSE: A copolymer, a molded product containing the copolymer, an adhesive containing the copolymer as an effective component and a laminate containing the copolymer are provided, to improve the balance of transparency, vibration resistance, viscoelasticity, adhesive property, flexibility and heat resistance of the copolymer. CONSTITUTION: The copolymer does not show crystallinity substantially and is a copolymer of ethylene and the vinyl compound represented by the formula 1, wherein R is a saturated hydrocarbon group, and the steric parameter Es of the R is -2.77 to -1.64 and the parameter B1 is 1.53 to 2.90. Also the copolymer has a structure whose carbons substituted with a substituent R are separated by a single methylene unit and is a copolymer of ethylene and the vinyl compound represented by the formula 1: CH2=CH-R, wherein R is a saturated hydrocarbon group, and the steric parameter Es of the R is -2.77 to -1.64 and the parameter B1 is 1.53 to 2.90.</p> |
