General description
羟丙基纤维素 (HPC) 在性质上具有生物相容性，并显示出较低的临界溶液温度 (LCST)。它是由纤维素与碱反应，生成碱纤维素，再与环氧丙烷连续反应制得的。HPC 溶于水，溶解度低于室温，粘度与温度呈反比关系。
Application
HPC 骨架组成的共聚物与 聚（2-二甲氨基）乙基甲基丙烯酸酯侧链已被合成用于基因传递。HPC 已被用作纳米结构锐钛矿膜的粘合剂。由 HPC 骨架和聚（N-异丙基丙烯酰胺）作为侧链制成的聚合物缀合物充当智能水凝胶。已有报告称 HPC 被作为胶水进行研究。

Cationic polymers have been of interest and importance as nonviral gene delivery carriers. Herein, well-defined comb-shaped cationic copolymers (HPDs) composed of long biocompatible hydroxypropyl cellulose (or HPC) backbones and short poly((2-dimethyl amino)ethyl methacrylate) (or P(DMAEMA)) side chains were prepared as

Hydroxypropyl cellulose (HPC) possesses a lower critical solution temperature (LCST) above 40 °C, while the poly(N-isopropylacrylamide) (P(NIPAAm)) exhibits a LCST of about 32 °C. Herein, comb-shaped copolymer conjugates of HPC backbones and low-molecular-weight P(NIPAAm) side chains (HPC-g-P(NIPAAm) or HPN) were
