The present invention relates to a terminal modified and conjugated diene-based polymer rubber composition including a terminal modified and conjugated diene-based polymer which is characterized in that an aminosilane-based terminal modifier represented by Formula 1 or Formula 2 is combined at the terminal of a conjugated diene-based polymer, and a method for preparing the same.

Method for preparing rubber composition using aminosilane-based terminal modifier introducing functional group, and rubber composition prepared thereby

Disclosed are an end-modified conjugated diene-based polymer configured such that the end of a conjugated diene-based polymer is coupled with an aminosilane-based end modifier, and a method of preparing the same.

Aminosilane terminal modifier to which functional group has been introduced, method for producing terminal-modified conjugated diene polymer using the aminosilane terminal modifier, and terminal-modified conjugated diene polymer produced according to the method

Aminosilane terminal modifier to which functional group has been introduced, method for producing terminal-modified conjugated diene polymer using the aminosilane terminal modifier, and terminal-modified conjugated diene polymer

In an apparatus for manufacturing a scaffold and a scaffold manufactured by the apparatus, a collector is disposed under a dispensing head that dispenses melted bio materials (polymer) for manufacturing the scaffold. The collector has a cylindrical tube shape. Both sides of the tube shape are fixed. Thus, the tube is securely fixed and bending of the tube is prevented. Also, accuracy and preciseness of the scaffold are improved.
