The present invention is directed to a mixture which can be used as an adhesive. The mixture broadly contains 1) a hydroxy group containing polyurethane, and 2) a polycarbonate and/or a polycaprolactone.

Polyurethane mixtures and the use thereof as adhesives

Adhesive mixture

A process for the manufacture of polyester polyalcohols with amino and amide groups by the reaction of polyester polyalcohols with polyamines is characterized in that unsaturated polyester polyalcohols if necessary in admixture with saturated polyester polyalcohols are used as polyester polyalcohols, and low molecular weight, aliphatic polyamines with two primary amino groups are used as polyamines.

Polyester polyalcohols containing amino and amide groups and poly (urea)

The production of impact-resistant polystyrene with EPDM simplifies the process and produces improved products if a modified ethylene/propylene rubber consisting of styrene/butadiene- or diene polymers, ethylene, optionally propylene and an unconjugated diene are used as the elastifying component. The modified EPDM rubbers consisting of (a) from 20 to 90% by weight of ethylene units, (b) from 1 to 25% by weight of units of a butadiene/styrene copolymer containing a quantity of from 10 to 90% by weight of styrene, (c) from 0 to 10% by weight of units of an unconjugated diolefin and (d) C.sub.3 -C.sub.18 .alpha.-monolefin units to make up the difference to 100% by weight, are a further subject of this invention.
