應(ying)用領域廣范，丙(bing)烯(xi)(xi)酸(suan)樹(shu)脂(zhi)(zhi)綜合(he)性(xing)(xing)能優異。但中高(gao)羥值的(de)丙(bing)烯(xi)(xi)酸(suan)樹(shu)脂(zhi)(zhi)由于極性(xing)(xing)大，跟醚(mi)化(hua)度(du)高(gao)的(de)氨基(ji)樹(shu)脂(zhi)(zhi)、醇(chun)酸(suan)樹(shu)脂(zhi)(zhi)、TDI加成(cheng)物固化(hua)劑混溶性(xing)(xing)較差，使丙(bing)烯(xi)(xi)酸(suan)樹(shu)脂(zhi)(zhi)的(de)通用性(xing)(xing)受到明顯(xian)的(de)限制。本(ben)文通過聚(ju)酯與丙(bing)烯(xi)(xi)酸(suan)樹(shu)脂(zhi)(zhi)的(de)共聚(ju)反應(ying)，有效(xiao)的(de)解決羥基(ji)丙(bing)烯(xi)(xi)酸(suan)樹(shu)脂(zhi)(zhi)與高(gao)、中、低(di)醚(mi)化(hua)度(du)氨基(ji)樹(shu)脂(zhi)(zhi)、醇(chun)酸(suan)樹(shu)脂(zhi)(zhi)、TDI加成(cheng)物固化(hua)劑的(de)混溶性(xing)(xing)問題，拓寬了丙(bing)烯(xi)(xi)酸(suan)樹(shu)脂(zhi)(zhi)的(de)應(ying)用范圍。

硬度、柔(rou)韌性、光澤等指(zhi)標亦可調節，   溶(rong)劑型丙(bing)烯酸(suan)樹(shu)脂(zhi)(zhi)由(you)于Tg值、羥值、酸(suan)值都(dou)可以調整。這給樹(shu)脂(zhi)(zhi)的應(ying)(ying)用(yong)提供了(le)較(jiao)大(da)的方便，拓寬了(le)該樹(shu)脂(zhi)(zhi)的應(ying)(ying)用(yong)領域，滿(man)足 人們多種多樣和(he)不斷提高的需求，所以，丙(bing)烯酸(suan)樹(shu)脂(zhi)(zhi)在國(guo)內還不過(guo)三(san)十年的歷史(shi)，油(you)漆應(ying)(ying)用(yong)領域卻發(fa)展(zhan)到僅(jin)次于醇酸(suan)樹(shu)脂(zhi)(zhi)第二大(da)用(yong)量樹(shu)脂(zhi)(zhi)體系，近年來國(guo)際(ji)原油(you) 價格不時上漲(zhang)，但對丙(bing)烯酸(suan)樹(shu)脂(zhi)(zhi)的發(fa)展(zhan)和(he)應(ying)(ying)用(yong)都(dou)未造成(cheng)明顯的沖擊，目前(qian)，該樹(shu)脂(zhi)(zhi)還無替代品(pin)，丙(bing)烯酸(suan)樹(shu)脂(zhi)(zhi)仍然是國(guo)內樹(shu)脂(zhi)(zhi)領域研(yan)發(fa)的重點。
