摘要：
Provided is a polymer blend in granular form and a process for making the blend. The blend is suitable for use as an additive in a variety of applications, such as in detergent formulations. The blend comprises: (i) one or more first polymers each independently having a weight-average molecular weight of 35,000 to 100,000 g/mol and each independently comprising polymerized units of (a) 22 to 80 wt % of one or more monoethylenically unsaturated C3-C6 carboxylic acid monomers, and (b) 20 to 78 wt % of one or more C1-C12 alkyl (meth)acrylate monomers; and (ii) one or more second polymers each independently having a weight-average molecular weight of 1,000 to 45,000 g/mol and each independently comprising polymerized units of 50 to 100 wt % of one or more monoethylenically unsaturated C3-C6 carboxylic acid monomers, wherein component (i) comprises from 1 wt % to 50 wt % based on the total weight of (i) and (ii), wherein the polymer blend is in granular form, and wherein one or more polymers of the polymer blend i
