Abstract

COMPOSITIPN WHICH ARE PARTICILARY ADAPTED FOR USE IN WAX FORMULATIONS ARE PREPARED BY POLYMERIZING, IN THE PRESENCE OR ABSENCE OF A CATALYST, 2-P-DIOXANONE WITH EITHER A POLYOL HAVING THE FORMULA R-(OH)N WHEREIN R IS A C2-C2-C6 ALKYL RADICAL AND N IS AN INTEGER OF FROM 2-6; AN ALIPHATIC MONOCARBOXYLIC ACID ESTER HAVING THE FORMULA R''- COOH WHEREIN R''NIS A C7-C19 ALKYL RADICAL; AN ALIPHATIC MONOCARBOXYLIC ACID ESTER HAVING THE FORMULA

R2-COO-R(-OH)N''

WHEREIN R IS AS DEFINED ABOVE, R2 IS A C2-C18 ALKYL RADICAL AND N IS AN INTEGER OF FROM 2-5; AN ALKYL; ETHER HAVING THE FORMULA R(OH)N-O-R-(OH)N OR

R(OH)N-O-R-(OH)N-O-R-(OH)N

WHEREIN R AND N'' IS AS DEFINED ABOVE; OR AN ETHER-ESTER HAVING THE FORMULA

R3-O-R(-OH)N"-OOC-R4

WHEREIN R IS AS DEFINED ABOVE. R3 IS A C1-C15 ALKYL, R4 IS A C-2C18 ALKYL, N" IS AN INTEGER OF FROM 2-4. THE POLYMER COMPOSITIONS CAN BE FORM 10:1 TO MOLE RATIO OF 2-P-DIOXANE TO POLYOL OR MONOCARBOXYLIC ACID, RESPECTIVE,Y. THE POLYMER COMPOSITIONS ARE CHARACTERIZED BY AN ACID NUMBER OF 10-50, A HYDROXYL NUMBER OF 10-75, A MOLECULAR WEIGHR OF 1200-300, A PENETRATION HARDNESS OF 1;5-10.0, AND A RING AND A BALL SOFTENING POINT OF 75*105* C.

Int. Cl. C08g 17/02 US. Cl. 26018 R No Drawing. 14 Pages Specification Compositions which are particularly adapted for use in wax formulations are prepared by polymerizing, in the presence or absence of a catalyst, 2-p-dioxanone with either a polyol having the formula R--(OH) wherein R is a C -C alkyl radical and n is an integer of from 2-6; an aliphatic monocarboxylic acid having the formula R-COOH wherein R is a -0 alkyl radical; an aliphatic monocarboxylic acid ester having the formula wherein R is as defined above, R is a C -C alkyl radical and nf is an integer of from 2-5; an alkyl ether having the formula R(OH), O--R(OH) or where R and n are as defined above; or an ether-ester having the formula 0 m-o-R-mrow-o-ii-m wherein R is as defined above. R is a C -C3 alkyl, R is a C -C alkyl, n is an integer of from 2-4. The polymer compositions can be from :1 to 90:1 mole ratio of 2-p-dioxanone to polyol or monocarboxylic acid, respectively. The polymer compositions are characterized by an acid number of 10-50, a hydroxyl number of 10-75, a molecular Weight of 1200-3000, a penetration hardness of -100, and a ring and ball softening point of C.
