    Abstract: Thermoplastic segmented elastomeric copolyether-esters which substantially consist of a plurality of recurring short-chain and long-chain ester units linked to one another by ester bonds, the proportion of the short-chain ester units of the formula I where R is the divalent radical remaining after removal of the carboxyl groups of aromatic dicarboxylic acids having a molecular weight of II where R is defined as above and B is the divalent radical remaining after removal of the terminal hydroxyl groups from a long-chain glycol, being from 25 to 85% by weight of the copolyester, and which contain from 0.01 to 5 mole %, based on copolyester, of trifunctional or more highly functional compounds, serving as branching agents, chemically incorporated into the polymer molecule. The copolyesters are particularly suitable for use in pressure-sensitive adhesives.

    Abstract: The copolymers have mol. wt. of 1000-10000 and a gel point of 15 degrees C, and are made by polymerising at 100-160 degrees C, at least temporarily under reduced pressure and at reflux, of a mixture of (a) 55-97 wt% acrylic acid esters of 3-12C non-tertiary alkanols; (b) 3-25 wt% of >=1 (meth)acrylic acid ester contg. a OH grp.; and (c) 0-20 wt% other monoethylenically unsatd. monomers, in the presence of free radical catalysts and opt. polymerisation regulators and solvents. The resulting polymers are completely compatible with polyetherols (made e.g. by reacting epoxypropane or epoxyethane with polyols) and may be used in plasticisers, e.g. in polyacrylates and polyurethanes, and in coatings, primers, adhesives and sealants.

    Abstract: 1463846 Pressure-sensitive adhesives BASF AG 6 June 1974 [7 June 1973] 25178/74 Heading C3P [Also in Division B2] Pressure-sensitive adhesives comprise (1) 80 to 30 weight per cent of an ethylene copolymer containing 25 to 50 weight per cent of methyl acrylate units and having a melt index of 10 to 100 g./10 min., and (2) 20 to 70 weight per cent of a tackifier resin. The tackifier resin may be a rosin or rosin derivative, terpene resin, ketone resin, coumarone resin, indene resin, petroleum resin, copolymer of styrene with vinyl toluene or isobutylene, or polyisobutylene. Examples describe adhesives comprising ethylene/methyl acrylate copolymers and (1 and 2) hydrogenated rosin, (3) hydroabietylphthalate, (4) hydrocarbon resin, (5) terpene/phenol resin, (6) pentaerythritol ester of hydrogenated rosin and (7) styrene/isobutylene copolymer.
