Claims
- 1. A polymeric composition comprising the product of the reaction of a polymerizable material in a free radical polymerization reaction which is initiated by a cyclobutarene peroxide, wherein cyclobutarene fragments derived from the cyclobutarene peroxide are incorporated into the product.
- 2. The polymeric composition of claim 1 wherein the polymerizable material comprises a monoalkenyl arene monomer, a conjugated diene monomer, acrylic or methacrylic acid, or a mixture of any two or more of these monomers.
- 3. The polymeric composition of claim 2 wherein the polymerizable material comprises styrene or an alkyl or halo substituted styrene.
- 4. The polymeric composition of claim 1 wherein the cyclobutarene peroxide comprises at least one cyclobutarene moiety linked through the aromatic ring to at least one peroxide containing group, the cyclobutarene peroxide being represented by the formula:
- (CBAr).sub.a --PCG
- wherein CBAr is a cyclobutarene moiety, PCG is a peroxide containing group and a is an integer of at least 1.
- 5. The polymeric composition of claim 4 wherein a is 1, and the peroxide containing group PCG is --R--OO--R.sup.1 and the cyclobutarene peroxide is represented by the formula: ##STR9## where R is a carbonyl, C.sub.2-10 acylene or C.sub.1-10 alkylene and R.sup.1 is C.sub.2-10 acyl or C.sub.1-10 alkyl and wherein cyclobutarene fragments derived from the cyclobutarene peroxide are part of the polymer.
- 6. The polymeric composition of claim 5 wherein the cyclobutarene peroxide is represented by any one of the formulae: ##STR10##
- 7. The polymeric composition of claim 4 wherein a is 2 and the cyclobutarene peroxide is represented by the formula: ##STR11## where R is R is carbonyl, C.sub.2-10 acylene or C.sub.1-10 alkylene wherein the cyclobutarene fragments derived from the cyclobutarene peroxide are incorporated into the product.
- 8. The polymeric composition of claim 7 wherein the cyclobutarene peroxide is represented by any one of the formulae: ##STR12##
- 9. A polymeric product produced by the ring opening polymerization reaction of the polymeric composition of claim 1.
