Claims
- 1. In a polymeric composition comprising a polymeric material and a plasticizing amount of a polymer, the improvement wherein the polymer is an anionically-polymerized addition polymer of at least one ester of methacrylic acid selected from the group consisting of (C.sub.1 -C.sub.24) alkyl esters of methacrylic acid, di(C.sub.1 -C.sub.4) alkylamino (C.sub.2 -C.sub.4) alkyl esters of methacrylic acid, (C.sub.2 -C.sub.12) alkoxyalkyl esters of methacrylic acid, (C.sub.7 -C.sub.12) aryloxyalkyl esters of methacrylic acid, (C.sub.7 -C.sub.12) aralkoxyalkyl esters of methacrylic acid, and (C.sub.7 -C.sub.10) aralkyl esters of methacrylic acid, and, optionally, other anionically copolymerizable monomers, wherein n, the average chain length of the polymer is about 6 to 50 mers.
- 2. The composition of claim 1 wherein the polymer has an average chain length of about 6 to about 25 mers and wherein at least about 85% by weight of the molecules of the polymer have chain lengths of about .sqroot.2n to about 2n mers.
- 3. The polymer of claim 1 wherein the ester is a (C.sub.1 -C.sub.24) alkyl methacrylate.
- 4. The polymer of claim 3 wherein the ester is methyl methacrylate.
- 5. The polymer of claim 1 wherein the ester is dimethylaminoethyl methacrylate.
- 6. A powder coating composition comprising a composition of claim 1 in powdered form and optionally comprising a pigment.
