What is claimed is: 1. A method of producing a molded article comprising: (i) mixing fibrids, floc, pulp, micropulp or a combination thereof with a composition to form a moldable component, said composition comprising: (a) an acetoacetylated polyvinyl polymer having the formula: wherein (m) ranges from about 1.5 mole percent to about 85 mole percent, (n) ranges from about 0 mole percent to about 20.5 mole percent, (p) ranges from about 12 mole percent to about 87 mole percent and (q) ranges from about 1 mole percent to about 88 mole percent, sum of (m), (n), (p) and (q) being 100 and wherein R1 and R2 are independently H, substituted or unsubstituted C1 to C12 alkyl, substituted or unsubstituted C6 to C14 aryl, substituted or unsubstituted C7 to C22 aralkyl, substituted or unsubstituted C6 to C14 alkaryl, substituted, unsubstituted C4 to C14 carbocyclyl or a combination thereof, said substituents being independently selected from the group consisting of C1 to C12 alkoxy, acyl, carboxyl, derivative of carboxyl, sulfonyl, derivative of sulfonyl, cyano, and halo; (b) an acetoacetylated polyvinyl polymer having the formula: wherein (m) ranges from about 1.5 mole percent to 85 mole percent, (n) ranges from about 0 mole percent to 20.5 mole percent, (p) ranges from about 12 mole percent to about 87 mole percent, (q) ranges from about 1 mole percent to about 88 mole percent and (x) ranges from 0. 5 to 6 mole percent, sum of (m), (n), (p), (q) and (x) being 100 and wherein R1 and R2 are independently H, substituted or unsubstituted C1 to C12 alkyl, substituted or unsubstituted C6 to C14 aryl, substituted or unsubstituted C7 to C22 aralkyl, substituted or unsubstituted C6 to C14 alkaryl, substituted, unsubstituted C4 to C14 carbocyclyl or a combination thereof, and wherein Z is H, or--COOH and Y is--COOH, halo, unsubstituted phenyl or a combination thereof; said substituents being independently selected from the group consisting of C1 to C 12 alkoxy, acyl, carboxyl, derivative of carboxyl, sulfonyl, derivative of sulfonyl, cyano, and halo; or (c) a combination thereof; (ii) heating said moldable component into a melt; (iii) conveying a desired amount of said melt into a cavity of an article mold; (iv) cooling said desired amount of melt to form said article; and (v) removing said article from said cavity. 2. The method of claim 1 wherein said molded article is a safety helmet.
