Abstract: Copolymers are prepd. by reacting together at elevated temps. a mixt. of (a) a cpd. contg. cyclopentadiene units (b) olefinically unsatd. aromatic cpds., and (c) and alpha, beta-olefinically unsatd. carboxylic acid cpd. Component (b) is used in an amt. of 5-50 mol % esp. 10-40 mol % on total compsn. and the mol. ratio components (c): (a)+(b) is 1:1 to 1:12. The reaction is pref. effected at 200-300 (esp. 230-270) degrees C opt. in an inert solvent and/or under pressure. Process is simple and gives prods. with a high thermal stability are useful as replacements for modified colophony resins in printing inks, giving fast drying and good gloss; as additives to paints, impregnating agents and textile aids; as low molecular additives in (hot melt) adhesives and in road marking compsns.

Abstract: Unsatd. polyester based binders are made by (1) in a first stage, reacting (a) >=1 single olefinically unsatd. dicarboxylic acid which is free from polymerisable aliphatic multiple bonds; (I); (b) >=1 polyhydric alcohol (II) and (c) >=1 polycyclic norbornane ring cpd. (III) with >=1 functional COOH, OH or amino gp., and (2) in a second stage, reacting the prod. with (d) >=1 condensable acrylic cpd. (IV). The modified acrylated polyesters are esp. useful as binders for UV-curable printing inks. The norbornane ring modification gives prods. with improved processability and improved storage stability in pigmented form. The binders have good pigment wetting characteristics, fast cure times and low viscosity and thus give fast drying high gloss prints with freedom from 'picking' (sticking of paper to the printing rollers).

Abstract: Carboxylated hydrocarbon resins for use as binders, esp. in printing inks, are prepd. by (a) preparing a hydrocarbon resin by cationically polymerising an olefinically unsatd. hydrocarbon with >=4C atoms, (b) reacting the resin with a non-aromatic olefinically unsatd. polycarboxylic acid, and (c) reacting the prod. with an unsatd. monomer without carboxyl or anhydride gps. to form a graft copolymer. Resins are obtd. in short reaction times. They have good solubility in org. solvents and give rapidly drying printings inks.

Abstract: Adhesive materials based on thermal copolymerisates of (A) 85-60 (90-70) wt.% cyclopentadiene units and (B) 5-40 (10-30)% vinyl esters of 1-18C monocarboxylic acids. The copolymers have av. mol. wt. 400-3000 and softening pt. 20-150 degrees C. Pref. (A) consists of a mixt. of cyclopentadiene units, =30 wt.% being 1-4C alkyl cyclopentadiene. (B) is pref. vinyl acetate. The copolymers have Br values of 60-120 and iodine colour values of 8-20. They are pref. catalytically hydrogenated at 200-230 degrees C under 20-300 (50-100) atmos. in hydrocarbon solvent or melt form, after which they have Br values below 20 and iodine colour values below 6. Used in combination with ethylene/vinyl acetate copolymers as hot melt adhesives, and in combination with natural rubber as press.-sensitive adhesives. They can be used in all types of adhesives to replace natural or terpene resins. In hot melt adhesives they show improved storage stability and higher bond strength to plastics, e.g. polyester, melamine and PVC, as well as wood. In solvent-based adhesives they give better adhesion and cohesion.
