This invention relates to a class of alkenylated toluenediisocyanates having at least one alkenyl group ortho to an isocyanate group. More particularly the toluendiisocyanates are represented by the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are hydrogen, C.sub.1-3 aliphatic, phenyl, halogen or alkoxy radicals, or R.sub.2 and R.sub.4 or R.sub.5 are bridged via an alkylene radical --(CH.sub.2).sub.y --wherein y=2 to 5, and x is one or two provided that in said formula at least one of R.sub.1, R.sub.2, R.sub.3, R.sub.4 or R.sub.5 is C.sub.1 or greater.The above described alkenylated toluenediisocyanates have been found to be well suited for preparing crosslinkable condensation polymers by providing pendant unsaturation for post curing and polymerization. They are also well suited for preparing polyurethane and polyurea elastomer systems.

摘要:
Polyalkylene carbonates are stabilized against oxidative degradation by the inclusion therein of 0.2-10%, preferably 1-5%, of peroxyl-reactive sulphur-containing additive. Such compounds, found to be effective, are 3-t-butyl-4-hydroxy-5-methylphenyl sulfide, diphenyl sulfide, diphenyl sulfoxide, diphenyl sulfone, di-(p-tolyl sulfide) and sulphur.
摘要:
Improved wet adhesion properties of water-based paints and coating compositions are obtained by incorporating into the polymeric resin emulsion systems employed in the formulation of such paints or coating compositions a monomeric compound having a terminal ureido group at one end thereof and a vinyl terminal group at the opposite end. Such incorporated monomeric compounds correspond to the general formula ##STR1## wherein R is H or CH.sub.3, U designates a cyclic or acyclic ureido or thioureido group and L designates a selected linking structure. In the simplest of such monomeric compounds, L is --CH.sub.2 --, as specifically represented by allyl urea. In other representative compounds the linking group L may be a polymethylene group - (CH.sub.2).sub.n --or the chain may contain one or more oxy (ether), amino, amido or carbonyl groups, provided that any carbonyl group (CO) present is not directly attached to U or to an ethylenic carbon atom nor is such ethylenic carbon directly attached to a nitrogen atom. Among preferred monomeric compounds imparting such improved wet adhesion are: N-Beta-allylaminoethyl ethylene urea, allyloxy-N-B-(1-ethylene ureido) ethyl acetamide, and allyl ester of N-ethyl-B-(1-ethylene ureido)-N-methyl carbamate. The polymer resin in the emulsion is one formed from one or more ethylenically unsaturated monomer compounds, such as acrylates and methacrylates, vinyl esters, vinyl chloride, mono- or di-ethylenic hydrocarbons; or copolymers, interpolymers or blends of these.
