    摘要: An alternating copolymer composed of at least one monomer of group (A) consisting of unsaturated esters of carboxylic acids and unsaturated ethers, and at least one monomer of group (B) consisting of conjugated vinyl compounds having nitrile or carbonyl radicals, is highly lactonized by treating with an inorganic or organic acid, as produced or after sapoinfication. A novel alternating copolymer composed of the group (A) monomer consisting of at least one unsaturated ether or a mixture of at least one unsaturated ether and at least one unsaturated ester of carboxylic acid, and at least one monomer of the group (B) is also proposed.
