Abstract: PROBLEM TO BE SOLVED: To provide a resin connector which is excellent in shock resistance, heat resistance, hydrolysis resistance, chemical resistance, and especially in flexibility by using polyketone polymer consisting of two repetitive units with specific composition and specifying the ratio between them to a specific value. SOLUTION: In manufacture of a polyketone resin connector, resin consisting of polyketone copolymer constructed of repetitive units represented by the formulas I, II, in which a ratio y/x ranges from 0.01 to 0.10, is molded into the connector. In the formulas, (x), (y) represent mole % in the polymer, and in consideration of a mechanical characteristic and anti-shock strength, the ratio y/x ranges from 0.01 to 0.10. The ratio y/x ranges from 0.03 to 0.10 desirably, and more preferably, ranges from 0.05 to 0.09. This kind of polyketone copolymer is provided with a melting point of 175-300 deg.C, and a preferable melting point is 210-270 deg.C. Furthermore, 1-100 parts by weight of elastomer with a glass transition temperature of 20 deg.C or less may be mixed with 100 parts by weight of polyketone.
