⑵、向步骤⑴共聚后的乳液中加入外层单体，70℃-95℃之间在进行聚合，凝聚、干燥，得PVC发泡人造革用发泡调节剂。
进一步地，步骤⑴中，两段乳液按重量百分比70-80:20-30进行共聚。
进一步地，一段乳液由如下重量百分比的单体构成：0-20%丙烯酸酯、10-20%甲基丙烯酸甲酯和60-80%甲基丙烯酸酯；另一段乳液由如下重量百分比的单体构成：80-100%甲基丙烯酸甲酯和0-20%丙烯酸丁酯。
进一步地，两段乳液的总单体重量: 去离子水为0.1～1.0 :1。
进一步地，步骤⑴中，乳化剂为烷基硫酸盐、烷基磷酸盐、烷基苯磺酸盐、聚氧乙烯烷基醚、聚氧乙烯烷基脂肪酸酯中一种或多种；总用量为多段乳液总重量的0.2－5％。
进一步地，步骤⑴中，乳化剂为阴离子乳化剂或阴离子乳化剂和非离子乳化剂的复配物，用量为多段乳液总重量的0.5％－3.0％。
进一步地，步骤⑴中，引发剂为过硫酸盐、有机过氧化物、偶氮类化合物中的一种，或与亚硫酸盐、亚硫酸氢盐、硫代硫酸盐中的一种构成氧化还原引发剂体系；用量为多段乳液总重量的0.1－2％。
进一步地，步骤⑴中，分子量调节剂为C4－C20的烷基硫醇，用量为多段乳液总重量的0.1－3％。
进一步地，具体操作过程为：
a、向搅拌的去离子水中，加入乳化剂、丙烯酸酯、甲基丙烯酸甲酯、甲基丙烯酸酯、分子量调节剂，通入氮气，升温至75℃，再加入引发剂，在75～95℃聚合；

一种如上所述PVC发泡人造革用发泡调节剂的制备方法制得的产品，其特性粘度为0.1-3.0，优选为0.1-2.0，更优选为0.1-1.0，最优选为0.2-0.5。
与现有技术相比，本发明具有以下优点：操作简单，制备出的超低分子量的丙烯酸酯共聚物，它能和含有增塑剂的PVC基体互溶，在基本不降低PVC基体流动性的情况下，增加PVC基体的熔体强度，能够促进PVC发泡皮革的发泡均匀度。
具体实施方式
下面结合实施例对本发明进行详细描述，本部分的描述仅是示范性和解释性，不应对本发明的保护范围有任何的限制作用。
一种PVC发泡人造革用发泡调节剂的制备方法，包括如下步骤：
