style="text-indent:25px">20世紀(jì)90年代初，美國提出先進(jìn)的固相接枝改性法，現(xiàn)已開發(fā)出相關(guān)產(chǎn)品，如伊士曼公司生產(chǎn)的氯化改性pp（mcpp）樹脂，在我國市場(chǎng)每噸售價(jià)高達(dá)50多萬元。改性pp（mpp）和mcpp作為特種pp**料，擴(kuò)展了pp的應(yīng)用范圍，具有極大的經(jīng)濟(jì)效益。采用固相接枝法對(duì)等規(guī)pp進(jìn)行改性得到mpp，然后對(duì)mpp進(jìn)行氯化即可獲得mcpp固體粉狀樹脂。氯化改性后的樹脂附著力強(qiáng)，接伸模量提高，易于與其他樹脂共混；而且由于改性使pp的結(jié)晶受到破壞，極性增加，從而可溶于某些溶劑，制得不同濃度的mcpp溶液。高抗沖pp塑膠原料源頭好貨均聚物型和共聚物型的pp塑膠原料材料都具有優(yōu)良的抗吸濕性、抗酸堿腐蝕性、抗溶解性。</p><div

style="text-indent:25px">共聚物型的pp塑膠原料材料有較低的熱變形溫度(100℃)、低透明度、低光澤度、低剛性，但是有更強(qiáng)的抗沖擊強(qiáng)度，pp塑膠原料的沖擊強(qiáng)度隨著乙烯含量的增加而增大。pp塑膠原料的維卡軟化溫度為150℃。由于結(jié)晶度較高，這種材料的表面剛度和抗劃痕特性很好。pp塑膠原料不存在環(huán)境應(yīng)力開裂問題。pp塑膠原料的熔體質(zhì)量流動(dòng)速率(MFR)通常在1~100。低MFR的pp塑膠原料材料抗沖擊特性較好但延展強(qiáng)度較低。對(duì)于相同MFR的材料，共聚型的抗沖強(qiáng)度比均聚型的要高。由于結(jié)晶，pp塑膠原料的收縮率相當(dāng)高，一般為1.6~2.0%。</p><p style="text-indent:25px">pp塑膠原料分子量分布對(duì)其物理力學(xué)性能和加工性能有重要影響。對(duì)于一般的擠出、注塑制品來說，分子量分布寬時(shí)，其加工性能較好，但拉伸強(qiáng)度差，伸長(zhǎng)率變小。對(duì)纖維級(jí)pp塑膠原料樹脂來說，則要求分子量分布窄些好，對(duì)成纖維性能和纖維質(zhì)量有益。纖維級(jí)pp塑膠原料樹脂的分子量分布指數(shù)要求在3和5之間。分子量分布表示高分子化合物中分子量的分散程度。分子量分布可用分子量分布指數(shù)來描述。分子量分布指數(shù)可以表示為重均分子量與數(shù)均分子量的比值，其值的大小范圍表示分子量分布寬和窄。pp塑膠原料材料完全可以使用熱流道系統(tǒng)。</p><div

style="text-indent:25px">熔噴料pp原料按熔噴料pp原料分子中甲基(-CH3)的空間位置不同分為等規(guī)、間規(guī)和無規(guī)三類。從立體化學(xué)來看，IPP分子中每個(gè)含甲基(-CH3)的碳原子都有相同的構(gòu)型，即如果把主鏈拉伸(實(shí)際呈線團(tuán)狀)，使主鏈的碳原子排列在主平面內(nèi)，則所有的甲基(-CH3)都排列在主平面的同一側(cè)。從立體化學(xué)來看，SPP分子中含有甲基(-CH3)的碳原子分為兩種不同構(gòu)型且交替排列，如把主鏈拉伸，使主鏈的碳原子排列在主平面內(nèi)，則所有的甲基(-CH3)交替排列在主平面的兩側(cè)。SPP是高彈性的熱塑性塑料，有良好的拉伸強(qiáng)度，它可以像乙丙橡膠(15480, -185.00, -1.18%)那樣進(jìn)行硫化成為彈性體，機(jī)械性能優(yōu)于一般不飽和橡膠。pp塑膠原料根據(jù)分子構(gòu)型不同，有等規(guī)熔噴料pp原料、間規(guī)熔噴料pp原料、無規(guī)熔噴料pp原料三種。供應(yīng)pp塑膠原料韓國曉星</p></p><br /><p>文章來源地址:
