Abstract:
A process for producing a degradable olefin copolymer, comprising reacting, in the presence of a metallocene complex of a Group IV, Group V, or Group VI transition metal and under polymerization conditions:(a) a first olefinic monomer of the form CH.sub.2 R.sup.1.dbd.CH.sub.2 R.sup.2, whereinR.sup.1 is hydrido or alkyl,R.sup.2 is hydrido, alkyl, alkenyl, aryl, alkaryl or halogen,or whereinR.sup.1 and R.sup.2 are linked to form --Q-- wherein Q is substituted or unsubstituted hydrocarbylene; and(b) a second olefinic monomer of the formCHR.sup.3.dbd.CH.sub.2 --(L.sup.1).sub.m --X--(L.sup.2).sub.n --CH.sup.2.dbd.CHR.sup.4whereinR.sup.3 and R.sup.4 are independently hydrido, alkyl, aryl or substituted aryl,L.sup.1 and L.sup.2 are optionally substituted hydrocarbylene groups,m and n are independently 0 or 1, andX is a group that is hydrolytically cleavable under aqueous conditions.
