Abstract:
A liquid organopolysiloxane resin of the average composition[R.sup.1 Si(CH.sub.3).sub.2 O.sub.1/2 ].sub.a [(CH.sub.3).sub.3 SiO.sub.1/2 ].sub.b [R.sup.2 O.sub.1/2 ].sub.c [R.sup.1 Si(CH.sub.3)O].sub.d [CH.sub.3).sub.2 SiO].sub.e [SiO.sub.2 ],whereinR.sup.1 is a C.sub.2 -C.sub.8 -alkenyl group,R.sup.2 is an optionally substituted, linear or branched C.sub.1 -C.sub.8 -alkyl group or mixture thereof,a+b+c+d+e is about 1 to 6,d+e is about 0.1-2the resin has a viscosity of 0.1 to 1000 Pas at 25.degree. C., andand the alkenyl content of the resin is in the range 0.4 to 4 mmol/g.
