    摘要: What is described herein is a process for making a copolymer of high specific viscosity by polymerization of maleic anhydride and a C.sub.1 -C.sub.4 alkyl vinyl ether monomer. The invention involves polymerizing said monomers to form a slurry of said copolymer in excess alkyl vinyl ether and toluene and is characterized by the steps of: (a) precharging a reactor with C.sub.1 -C.sub.4 alkyl vinyl ether as solvent at a reaction temperature, (b) feeding a mixture of maleic anhydride and a C.sub.1 -C.sub.4 alkyl vinyl ether in substantially stoichiometric amounts, preferably with a slight excess of the alkyl vinyl there, and at a selected rate, into said precharged reactor, and (c) simultaneously feeding a predetermined mixture of toluene and a polymerization initiator continuously over substantially the entire period of polymerization.

    摘要: What is described herein is an improved precipitation polymerization process and copolymer products produced thereby. The process herein is carried out by charging a reactor with a solvent in which the copolymer product is substantially insoluble over the entire compositional range of the copolymer, preferably heptane or cyclohexane, and a polymerization initiator, heating to 50.degree. to 150.degree. C., agitating, and then simultaneously feeding selected amounts of a vinyl lactam and a polymerizable carboxylic acid into said reactor below the surface of the solvent while continuing to agitate the mixture to precipitate the copolymer from solution as a fine, white powder, and recovering the copolymer of defined composition.

    摘要: What is described herein is a solution feed, slurry precipitation polymerization process for making copolymers of maleic anhydride and an alkyl vinyl ether within a predetermined viscosity range.The process of the invention is characterized by precharging a large excess of the alkyl vinyl ether in a reactor, feeding maleic anhydride dissolved in a minimum amount of an organic solvent into the precharged reactor, and polymerizing the monomers in the presence of a free radical initiator. The copolymer product then appears as a pumpable slurry in the reaction medium. The slurry is discharged from the reactor and the desired copolymer is obtained therefrom as a fine, white powder having specific viscosities in the range of about 1.5-6.0, and preferably about 2.6-3.5.
