順丁(ding)(ding)(ding)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)是順式-1,4-聚丁(ding)(ding)(ding)二(er)烯橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)的(de)(de)簡稱(cheng)，其(qi)分子(zi)式為(wei)(C4H6)n。順丁(ding)(ding)(ding)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)是由丁(ding)(ding)(ding)二(er)烯聚合而(er)成(cheng)(cheng)的(de)(de)結(jie)(jie)構規(gui)整(zheng)的(de)(de)合成(cheng)(cheng)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)，其(qi)順式結(jie)(jie)構含量(liang)在95%以上。根據催(cui)化劑的(de)(de)不同，可(ke)分成(cheng)(cheng)鎳系(xi)、鈷系(xi)、鈦系(xi)和稀土(tu)系(xi)（釹(nv)系(xi)）順丁(ding)(ding)(ding)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)。順丁(ding)(ding)(ding)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)是僅(jin)次于丁(ding)(ding)(ding)苯橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)的(de)(de)第(di)二(er)大(da)合成(cheng)(cheng)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)。與天然(ran)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)和丁(ding)(ding)(ding)苯橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)相比(bi)，硫化后其(qi)耐(nai)(nai)寒性、耐(nai)(nai)磨性和彈性特別優(you)異，動負(fu)荷下發熱少，耐(nai)(nai)老化性尚(shang)好，易(yi)與天然(ran)橡(xiang)(xiang)(xiang)(xiang)、氯丁(ding)(ding)(ding)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)或丁(ding)(ding)(ding)腈橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)并用(yong)。順丁(ding)(ding)(ding)橡(xiang)(xiang)(xiang)(xiang)膠(jiao)(jiao)特別適用(yong)于制造(zao)汽車(che)輪胎和耐(nai)(nai)寒制品(pin)，還可(ke)以制造(zao)緩(huan)沖材料及各種膠(jiao)(jiao)鞋(xie)、膠(jiao)(jiao)布、膠(jiao)(jiao)帶(dai)和海綿膠(jiao)(jiao)等。
