The present disclosure is directed to polymer blends comprising a biopolymer and a substituted or unsubstituted aliphatic polyester. The aliphatic polyester comprises repeating units derivable from a substituted or unsubstituted aliphatic diacid, repeating units derivable from a substituted or unsubstituted aliphatic diol, and one or two terminator units derivable from a substituted or unsubstituted aliphatic alcohol. The polymer blends disclosed herein provide improved flexibility, and are useful, for example, in the production of packaging materials, industrial products, durable goods, and the like.

Biopolymer compositions having improved flexibility

A method of decreasing the UV light degradation of a UV-light degradable polymer comprising adding to said polymer an effective amount of a compound of formula (IX): wherein, R, Rand Rare the same or different and are selected from the group consisting of C-Calkyl, C-Ccycloalkyl, substituted alkyl, substituted cycloalkyl, ester, aryl, heteroaryl, heterocycloalkyl, substituted aryl, substituted heteroaryl, substituted heterocycloalkyl, and amino; Rand Rare the same or different and are selected from the group consisting of C-Calkyl, C-Ccycloalkyl, substituted alkyl, substituted cycloalkyl, ester, aryl, heteroaryl, heterocycloalkyl, substituted aryl, substituted heteroaryl, substituted heterocycloalkyl, cyano, and amino; Rand Rare the same or different and are selected from the group consisting of substituted diphenylmethylene, unsubstituted diphenylmethylene, substituted 9H-fluorene, and unsubstituted 9H-fluorene; t and u are each in the range of 1 to 100; s is in the range of 0 to 100; and a, b, c, and d are each in the range of 0 to 4.

Method of decreasing the UV light degradation of polymers

A thermoplastic polymer/elastomer composite composition including one or more thermoplastic polymers, a natural or synthetic rubber, and a long chain cyclic dimerate ester and/or long chain cyclic trimerate ester plasticizer.

Low polarity dimerate and trimerate esters as plasticizers for thermoplastic polymer/elastomer composites

An elastomeric composition including a natural or synthetic rubber, and a cyclic dimerate ester and/or a cyclic trimerate ester plasticizer.

Low polarity dimerate and trimerate esters as plasticizers for elastomers

Polymers and compounds including a diphenylmethylene or a 9H-fluorene moiety; and sunscreen compositions including a mixture of a photoactive compound and any one of the foregoing derivatives are disclosed herein. Also disclosed are methods for stabilizing a sunscreen composition by the addition of one or more of the foregoing derivatives, methods of filtering out ultra-violet light from a substrate by the use of one or more such derivatives, and methods for terminating a polymerization reaction by the addition of derivatives of diphenylmethylene and/or 9H-fluorene. Synergistic combinations of the polymer with (1) diesters or polyesters of a naphthalene dicarboxylic acid, or (2) oxybenzone enhance the photostability of sunscreen compositions containing a photodegradable sunscreen active compound, such as avobenzone.

Photostabilizers, UV absorbers, and methods of photostabilizing a sunscreen composition

Polymers and compounds including a diphenylmethylene or a 9H-fluorene moiety; and sunscreen compositions including a mixture of a photoactive compound and any one of the foregoing derivatives are disclosed herein. Also disclosed are methods for stabilizing a sunscreen composition by the addition of one or more of the foregoing derivatives, methods of filtering out ultra-violet light from a substrate by the use of one or more such derivatives, and methods for terminating a polymerization reaction by the addition of derivatives of diphenylmethylene and/or 9H-fluorene.

A method of preparing a sunscreen including a solvent system and a filter system, the method including the step of controlling the polarity of the solvent system to control the rate of photodecay of the filter system, as well as sunscreen compositions and compounds for producing sunscreen compositions, are disclosed.
