这个侧链和基部间的特定的相互作用便是氢键。
The specific interactions between side chains and bases are hydrogen bonds.
但因大分子链的分子内和分子间易形成氢键，所以不宜溶于许多有机溶剂，加工成型性能较差。
Because there are many hydrogen bonds between intramolecular and intermolecular chains, they cannot dissolve in many organic solvents, and their processing performance is poor.
