An implant material for replacing hard tissue containing as essential components

Implant materials for hard tissue

New polymers with K values of from 20 to 140, in which the side chains contain optically active 1,6,6-trimethylnorpinanyl-2-methyl or 3-pinanyl-methyl groups, so that the polymers are also optically active. The polymers are used for the production of coatings and adhesives, as optical modifiers for films, and for finishing paper and textiles.

Optically active polymers containing methylpinane groups

A process for the manufacture of reactive polymers of vinyl monomers by reacting the latter, or the polymers formed therefrom, with compounds which form free radicals. The latter compounds are tetrakis-(organylthio)-methanes, 1,1,2,2-tetrakis-(organylthio)-ethanes or hexakis-(organylthio)-ethanes. The polymers obtained can readily be modified, e.g. by oxidation or quaternisation.

Polymerization initiators containing thio bridges

Copolymers which have a molecular weight of from 600 to 24,500, and which contain from 0.1 to 60 per cent by weight of succinic acid hydrazide units and from 99.9 to 40% by weight of one or more ethylenically unsaturated monomers which are copolymerizable with maleic anhydride, are used as coating agents and binders.

Coating processes, compositions and substrates coated with maleic

Polyfunctional polymers of which the side branches contain dioxathiazole-2-oxide groups are described. They possess the reactivity of dioxathiazole-2-oxide and can in addition contain other reactive groups. They can be used for the manufacture of moldings, coatings or adhesives.

Polymers containing dioxythiazole-2-oxide groups

Polymers of which the side chains contain urethane groups and which have the reactivity of a urethane but can, in addition, contain other reactive groups. The new polymers may be used to produce moldings, coatings or adhesives.

Polymers containing urethane groups

Polymers which have formamide groups in the side branches and which may in addition contain other reactive groups. They can be used to produce moldings, coatings or adhesives.

Polymers containing formamide groups

Polymers which contain hydroxamic acid-O-sulfonyl groups in the side chains and which accordingly can undergo important substitution reactions. The polymers may also contain other reactive groups and may be used for the manufacture of moldings, coatings or adhesives.

Polymers containing hydroxamic acid-o-sulfonyl groups

Polymers containing units of the general formula: ##EQU1## in which X denotes --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --, ##SPC1## or divalent C.sub.3.sup.+10 cycloalkyl,
