  • Preparation of 1,4-butanediol mono(meth)acrylate by esterification of (meth)acrylic acid with 1,4-butanediol, in which an aqueous solution of unconverted 1,4-butanediol is obtained
    Patent number: 5637760
    Abstract: 1,4-butanediol mono(meth)acrylate is prepared by esterification of (meth)acrylic acid with 1,4-butanediol, by a process in which an aqueous solution of unconverted 1,4-butanediol is obtained, wherein the 1,4-butanediol present in the aqueous solution is converted into readily volatile tetrahydrofuran in the presence of a catalytic amount of a strong acid and the tetrahydrofuran is separated off from the aqueous solution.

  • Aqueous polyacrylate dispersions and their use for the production of self-adhesive structures having good low temperature adhesion
    Patent number: 4898909
    Abstract: Aqueous dispersions of copolymers having a glass transition temperature of not more than -45.degree. C. and a K value greater than 80 consist of not less than 80% by weight of acrylates of alkanols of 8 to 12 carbon atoms, from 1 to 4% by weight of .alpha.,.beta.- monoolefinically unsaturated carboxylic acids and/or their amide derivatives and from 0.1 to 3% by weight of .alpha.-methylstyrene, and are used for the production of self-adhesive structures having good tack at as low as -40.degree. C.
