Tributylborane in different concentrations was used for synthesis of gelatin and polyacrylamide graft-copolymer. The copolymers were characterized by Fourier transform infrared spectroscopy method (FTIR). The share of the graft polyacrylamide and the molecular weight of the copolymer increases with the alkylborane concentration growth. The polymers under study exhibit a single phase transformation caused by devitrification. Also, the glass transition temperature depends on tributylborane concentration and differs from that the initial homopolymers. It is supposed, that the grafting process occures through the mechanism of reversible inhibition due to active centers formed as a result of gelatin hydroxyl groups borylation. The excess of tributylborane may result the formation of additional radicals source: alkylborane – oxygen system.

使用不同浓度的三丁基硼烷来合成明胶和聚丙烯酰胺接枝共聚物。通过傅里叶变换红外光谱法（FTIR）对共聚物进行表征。接枝聚丙烯酰胺的份额和共聚物的分子量随着烷基硼烷浓度的增加而增加。所研究的聚合物表现出由失透引起的单相转变。而且，玻璃化转变温度取决于三丁基硼烷的浓度并且不同于初始均聚物的温度。据推测，接枝过程是通过可逆抑制的机理发生的，这是由于明胶羟基硼化作用形成的活性中心所致。过量的三丁基硼烷可能导致形成其他自由基源：烷基硼烷–氧气系统。
