Procedure

Into a reaction vessel was added a solution of 72.6g of ethylacrylate, 93g of butylacrylate, 3.8g of acrylic acid, 5g of azo-bis-isobutylronitrile and 0.68g of lauryl mercapan. Initially, 10g were added and the solution was heated up until the induction period had passed. The main portion was then added at a rate so that the internal temperature remained between 125-130° C. The addition was carried out over a period of one hour, after which time the polymer material could be stirred easily. The polymer material remains a clear but viscous liquid at 25° C., with comonomer proportions of 54.5:43.1:2.4.
