Abstract: This invention relates to radically hardening adhesives, which contain polymerisable isocyanates and which are distinguished by high adhesive capacity on plastics materials.

Abstract: This invention relates to stabilized adhesives, to which silyl esters are added for stabilization.

Abstract: This invention relates to adhesives which contain acrylic acid derivatives of 5,6-dihydro-dicyclopentadienol. These adhesives belong to the class of radically hardening adhesvies.

Abstract: A composition which is heat curable to give an elastomer of improved properties comprising(a) an organopolysiloxane polymer having a viscosity of 1,000,000 to 200,000 mPas at 25.degree. C. and comprising the structural unit ##EQU1## wherein R is a hydrocarbon radical or a halohydrocarbon radical, anda is between about 1.95 and 2.01,(b) a polycarbodiimide-polysiloxane copolymer comprising a polysiloxane continuous liquid phase containing a discontinuous phase of finely dispersed polycarbodiimide particles produced by condensing a diisocyanate in the polysiloxane,(c) a curing catalyst, and(d) a filler,the polycarbodiimide comprising about 0.1 to 80% by weight of (a) plus (b). Upon curing, the permanent set of the elastomer is reduced and/or the resistance to hydrolytic degradation is improved.

Abstract: In a polysiloxane rubber composition which vulcanizes under heat to form an elastomer and comprising(a) a polyorganosiloxane containing unsaturated radicals,(b) a compound containing Si-H groups,(c) a platinum-containing addition catalyst, and(d) an organic peroxide, the improvement which comprises(e) a compound capable of forming a complex ligand with platinum, whereby the storability of the composition is improved.

Abstract: In a polysiloxane molding composition which can be cured to give flame-repellent products, comprising(a) a diorganopolysiloxane of the formula ##EQU1## in which n is 1.9 to 2.05, andR.sup.1 is an alkyl, alkenyl and/or or aryl radical with 1-8 C-atoms,(b) finely divided TiO.sub.2 with a surface area, measured by the BET method, greater than 20 m.sup.2 /g and a particle size less than 0.5 .mu.m,(d) platinum and/or one of its sulphur-free compounds, and(e) a curing agent,the improvement which comprises about 0.05 to 10% by weight of (a) to (e) of nitrogen compound of the formula ##STR1## in which R is H, phenyl, alkyl with 1-6 C-atoms, tolyl, nitrile, --NHR.sup.2, --CH.sub.2 OR.sup.2, --CH.sub.2 COOR.sup.2, --C(.dbd.NH)NHR.sup.2, --CO--NH--R.sup.2 or (R.sup.1).sub.2 C--,R.sub.2.sup.1 is H, alkyl with 1-6 C-atoms, Si(CH.sub.3).sub.3 -- or R,R.sup.2 is H or --CO--R, andZ is NH, O or NR,or a salt thereof. Articles molded therefrom and then cured are of enhanced flame-repellency.
