Abstract: PURPOSE: A manufacturing method of soluble poly(glycolide-paradioxane) copolymer is provided to obtain high molecular weight copolymer material having low modulus and low stiffness by producing segmented star type copolymer with glycolide, paradioxane and primary multivalent alcohol. CONSTITUTION: A copolymer has segmented star type structure by using multivalent alcohol having three and more hydroxylic groups as an initiator during polymerizing paradioxane and glycolide under a catalyst. The segmented star type structure of the copolymer is caused by reaction difference of multivalent alcohol, glycolide and paradioxane. During polymerizing, poly(p-dioxane) homopolymer and p-dioxane monomer are generated from paradioxane monomer. The mixture reacts to glycolide. The glycolide is injected into the mixture of poly(p-dioxane) homopolymer and p-dioxane monomer to react at a rising temperature until a copolymer is generated. The reaction temperature is about 120-180deg.C and preferably 120-150deg.C. The polymerization is completed for 1-4h within the reaction temperature range. The glycolide ratio to the mixture of poly(p-dioxane) homopolymer and p-dioxane monomer is 3-25wt% and preferably 5-20wt%. The obtained copolymer has low modulus and low stiffness by having the segmented star type structure.

Abstract: A method of forming a diamond-like carbon coating in vacuum, comprising the steps of: pretreatment of the surface of the part; placing the part into a vacuum chamber; treating the surface of the part with accelerated ions; applying a sublayer of a material onto the treated surface of the part; electric arc vacuum sputtering a graphite cathode form a cathode spot and producing a carbon plasma; accelerating an ion component of the carbon plasma; depositing the produced carbon plasma on the surface of the part and producing the diamond-like carbon coating. A pulsed electric arc discharge is used, by which a plurality of cathode spots are excited at the end surface of the graphite cathode, said cathode spots moving along the end surface of the cathode at a speed of from 10 to 30 m/s and generating a carbon plasma having an ion energy of 40 to 100 eV and an ion concentration in the plasma of 10 12 to 10 14 cm -3, with electrically insulating the part in the vacuum chamber. The temperature of the part is maintained in the range of 200 to 450 K by controlling the repetition frequency of discharge pulses.
